Three Gorges Dam
EnergyThe world's largest hydropower station by installed capacity, at 22.5 GW, and the main flood-control structure on the Yangtze.
Geographically the third smallest state in Europe (after the Holy See and Monaco), San Marino also claims to be the world's oldest republic. According to tradition, it was founded by a Christian stonemason named MARINUS in A.D. 301. San Marino's foreign policy is aligned with that of the European Union, although it is not a member; social and political trends in the republic track closely with those of its larger neighbor, Italy.
The National Infrastructure Index maps the physical assets national life runs on — power stations and grids, water systems, ports, railways and airports, data networks, payment systems and launch sites. Each asset is placed in a Strategic Infrastructure capability group, so it can be read against the ratings in the National Capability index above.
Assets are chosen for how much of the economy and state depends on them and how hard they would be to replace. Each card records what the asset is, the category it belongs to, what it does and where it is.
Example assets. These twenty cards are modelled on China's most critical infrastructure and show on every nation page until each nation's own assets are mapped.

The National Development Index tracks the events that move a nation's capability — policy decisions, technological milestones, economic turns and external shocks — and places each one on the record with the date it happened and what followed from it. It is the narrative counterpart to the indices: where a rating says where San Marino stands, the index says how it arrived there.
Recent developments cover the current cycle, close enough that their consequences are still unfolding. Historical developments are the inflection points behind the present position — the decisions and events a reader needs in order to read the ratings above in context.
According to tradition, the stonemason fled religious persecution in Rimini and built a chapel on the mountain in 301 AD, and the settlement he founded became the basis for San Marino's claim to be the world's oldest surviving republic. Historians regard the story as part legend, noting a monk is recorded living on the mountain by 511.
Eugippus noted that another monk had lived in a monastery in the area, providing the first documentary trace of settlement. This is the earliest historical, as opposed to legendary, evidence for the community that became San Marino.
Governing authority was vested in the Grand and General Council, the body that remains San Marino's parliament. This established the representative framework of the republic.
The Captains Regent, still elected every six months by the Grand and General Council, trace their origin to 1243, replacing the earlier Arengo assembly of family heads as San Marino's system of government took shape. The republic's earliest written statutes date from 1263.
San Marino appealed to Bishop Ildebrandino Guidi di Romena against contribution demands by the Vicario del Montefeltro, and jurist Palamede di Rimini ruled in its favour. The judgment established a legal precedent of fiscal immunity that anchored later claims to autonomy.
The corps, originating as a military formation, has provided ceremonial crossbow shooting since the late 13th century. It survives as one of the republic's oldest continuous institutions.
Abbot Ranieri di Sant'Anastasio was appointed to judge a lengthy process using witnesses and documents to determine San Marino's tax status. The verdict was probably favourable, as the state thereafter paid no taxes to Montefeltro, consolidating its practical independence.
Official documents from the late 14th century record the business transactions of Jews in the republic. Further records from the 15th to 17th century verify a continuing Jewish community.
The neighbouring community voluntarily accepted incorporation into San Marino. This was the first territorial enlargement of the state beyond Monte Titano.
The inclusion of four further communities enlarged the republic to its present extent. The frontiers established then have remained unchanged ever since, giving San Marino unusual territorial continuity.
The son of Pope Alexander VI seized San Marino until Pope Julius II intervened and restored its independence. The episode showed both the vulnerability of the microstate and the value of papal patronage in preserving it.
Infantry and cavalry sent against San Marino became disoriented in dense fog and abandoned the attempt. The Sammarinesi credited Saint Quirinus, whose feast day it was, reinforcing the republic's providential self-image.
The absorption of Urbino removed San Marino's other neighbour and made the Papal States its sole frontier. This strategic encirclement shaped the republic's diplomacy for the following two centuries.
Surrounded by papal territory, the republic obtained a formal protectorate arrangement. It never amounted to de facto papal control, and San Marino retained self-government.
Alberoni, the papal governor of Ravenna, seized the republic on 17 October 1739, but civil disobedience and appeals to Rome led Pope Clement XII to recognise San Marino's rights again on 5 February 1740. That date, the feast of Saint Agatha, is still marked as a patron saint's day.
Known locally as the Guard of Nobles, the unit was raised to attend the council and the captains regent. It remains part of the republic's small ceremonial military establishment.
With the French army advancing into Italy, Regent Antonio Onofri won Napoleon's respect and a written promise, conveyed to Gaspard Monge, to protect San Marino's independence and even extend its territory; the guarantee was secured in the context of the Treaty of Tolentino. The regents declined the offer of land, fearing later revanchism from neighbouring states, and Napoleon also exempted Sammarinese citizens from taxation and sent grain. The republic's survival amid the upheaval of the French Revolutionary Wars and the Napoleonic reordering of Italy became a foundation of its later diplomatic standing.
The 1815 settlement confirmed San Marino's sovereignty alongside the wider reordering of Europe following the Napoleonic Wars. Further attempts to absorb the republic into the Papal States failed in 1825 and 1853.
The Gendarmerie was created to provide policing for the republic. It remains a core component of San Marino's internal security apparatus.
The treaty formalised relations with the newly unified Italian state that now surrounded San Marino, and began a series of conventions regulating economic activity in Sammarinese territory. It secured recognition of independence at the moment of Italian unification and remains the foundation of the bilateral relationship.
Capital punishment was formally abolished, though it had not been used since the 1400s. The measure gave the republic an early and lasting reputation in human rights.
A postal accord allowed the republic to issue stamps in its own name, displaying national symbols such as the Three Towers. Philately became a significant source of state revenue and an instrument of sovereign visibility.
Italy viewed Sammarinese neutrality with hostility, suspecting Austrian spies might use the republic's new radiotelegraph station, and cut its telephone lines after failing to station Carabinieri there. Twenty volunteers nonetheless served with Italian forces, and the Sammarinese Red Cross field hospital led Austria-Hungary to suspend diplomatic relations.
Postwar unemployment and inflation sharpened class tension, and middle-class fear of concessions to the lower-class majority fed support for the new party. Its creation set the stage for two decades of authoritarian rule.
PFS rule lasted twenty years, during which the party repeatedly sought support from Mussolini's government. It represented the longest interruption to San Marino's pluralist tradition.
The 31.5-kilometre line connected Rimini with the City of San Marino via Dogana, Serravalle, Domagnano and Borgo Maggiore. It was destroyed during the wartime bombing, leaving the republic without rail transport.
Three days after the fall of the Fascist regime in Italy, the PFS government collapsed and a new administration proclaimed neutrality in the war. The PFS briefly regained power on 1 April 1944 but maintained the neutral stance.
Four waves of Allied aircraft struck the republic in the mistaken belief it was occupied by German forces storing munitions. The government protested the same day that no military installations or belligerent forces were present; smaller raids continued until 29 August, badly damaging the city centre and the railway to Rimini.
Allied bombers mistakenly struck the neutral republic on 26 June 1944, and German troops invaded on 13 September despite its declared neutrality, leading to fighting between German and Allied forces later that month in the Battle of San Marino, in which the Germans were driven out. Allied forces then occupied the country for about two months before departing and full self-government was restored. San Marino had meanwhile sheltered more than 100,000 refugees, roughly seven times its own population of about 15,000.
A coalition of the Sammarinese Communist and Socialist parties governed from 1945 until a crisis known as the Rovereta affair ended its rule in 1957. The Communist Party later dissolved in 1990 and reformed as a social-democratic party, replacing its hammer-and-sickle emblem with a Picasso dove.
A service linking a heliport at Borgo Maggiore with one by Rimini's port was inaugurated on 30 June, following first flights from the site in September 1950. Extended to San Leo in 1964, the line closed in 1969.
The revision added to a run of improved assessments from credit rating agencies during 2025 and 2026, reflecting efforts to strengthen public finances and shed San Marino's reputation as a weak link in European banking.
The agency's research update pointed to stronger external and net debt metrics and kept the outlook stable. The move followed years of downgrades after the 2007–08 financial crisis exposed weaknesses in San Marino's banking sector.
Biordi, who died on 2 May 2026, had served two terms as one of San Marino's two joint heads of state, in 1981–82 and 1985–86, and was remembered as a long-standing member of the Grand and General Council.
Mularoni's death on 29 May 2026 came less than a month after that of fellow former captain regent Ubaldo Biordi, prompting tributes to two figures who had each led San Marino's twin-headed system of government.
The pair took office on 1 April 2026 for the customary six-month term, continuing a system dating to 1243 in which the Grand and General Council elects two joint heads of state twice a year.
Alpine skier Rafael Mini carried the flag at the Games, held from 6 to 22 February 2026, marking San Marino's 12th Winter Olympics appearance since its 1976 debut. Officials said tougher qualifying standards made earning a place doubly significant.
The determination on 24 December 2025 followed the conclusion of negotiations, agreed jointly with Andorra, in 2023. It complicated the treaty's path into force after a decade of talks aimed at integrating the microstate more closely with the EU's internal market.
The Fund's executive board completed its review on 21 November 2025, part of regular surveillance of an economy still recovering from a banking crisis that followed the 2007–08 global downturn. San Marino's per-capita GDP had reached around 62,000 US dollars, among the highest in the world.
The pair took office on 1 October 2025 for a six-month term as joint heads of state, chosen from opposing parties under a system intended to balance power between San Marino's political factions.
The recognition on 23 September 2025 aligned San Marino with a wave of Western states recognising Palestinian statehood around that month's UN General Assembly session.
Rondelli, aged 58, took office as one of the two heads of state on 1 April 2022. San Marino has had more female heads of state than any other country, 15 as of October 2014.
The pair's silver at the delayed 2020 Tokyo Olympics, awarded in 2021, gave San Marino, then with a population of about 34,000, its first Olympic medal in any category. Myles Amine added a wrestling bronze days later, San Marino's third medal of the Games.
The country's mean score of 0.01 out of 10 ranked it last of 172 countries assessed. The figure reflects the near-total human transformation of its 61 square kilometres of territory.
The reform followed the abolition of anonymous companies in 2010 and closer cooperation with the Council of Europe and the EU against money laundering. San Marino was subsequently removed from Italy's tax-haven blacklist in 2014 and the EU's in 2017.
The most significant of the bilateral aviation agreements gave San Marino long-term rights at the Rimini airport. As of August 2023 Sammarinese authorities still had no presence there.
A section of the former Rimini line was restored in the City of San Marino, running between Piazzale della Stazione and near Via Napoleone through the 502-metre Montale tunnel. It is the republic's only railway.
The census was held in 2010 with results expected by the end of 2011, but 13 per cent of families failed to return their forms. The gap of over three decades left the state with limited demographic data.
The listing recognised the historic core and the three towers of Monte Titano. It strengthened the republic's tourism sector, which contributes over 22 per cent of GDP.
The reform pushed parties into two alliances: the right-wing Pact for San Marino and the left-wing Reforms and Freedom. The Pact won the ensuing general election with 35 seats to 25 in the Grand and General Council.
Tomassoni took office as one of the two heads of state on 1 October 2007. His election marked a notable widening of representation in the republic's highest office.
The purchase of a holding in the management company Aeradria led to the airport being officially renamed Rimini-San Marino Airport. It formed part of a series of bilateral agreements since the 1980s over Sammarinese access to air transport.
The gallery holds more than 1,000 works dating from the first decade of the 20th century to the present. It is a principal cultural institution of the republic.
Membership followed San Marino's accession to the Council of Europe in 1988, during which it briefly held that organisation's rotating chair. The republic had previously conducted much of its diplomacy through Italy.
Although not an EU member, San Marino concluded cooperation and customs agreements with the European Community in 1991 and its foreign policy is aligned with that of the EU, while social and political trends in the republic track closely with those of its larger neighbour, Italy.
Membership brought the microstate into the principal European human rights and legal framework. In the same year an apostolic nunciature to the republic was formally established, vested in the nuncio to Italy.
The 1987 statute gave the Guard of the Rock a policing role alongside its military duties. Its members now assist in investigating major crime.
The grass runway at Torraccia was first used in 1981 and the airfield's structure opened in 1985, giving the republic a general aviation facility close to the Italian border. The runway was extended to 650 metres in July 2012.
A personal income tax was established, later reformed significantly in 2013 to enhance fiscal revenue. Rates now run from 9 per cent on the lowest incomes to 35 per cent above 25,000 euros.
The border between Montefeltro and Rimini was readjusted, placing the entire republic in the historic diocese of Montefeltro, renamed accordingly. This aligned ecclesiastical and civil boundaries in the overwhelmingly Catholic state.
The funivia opened on 1 August 1959 and now carries around 500,000 passengers a year over some 21,000 trips. It was modernised with double load-bearing cables in 1995–96 and renovated again in 2017, underpinning the tourist economy.
Geographically the third smallest state in Europe (after the Holy See and Monaco), San Marino also claims to be the world's oldest republic. According to tradition, it was founded by a Christian stonemason named MARINUS in A.D. 301. San Marino's foreign policy is aligned with that of the European Union, although it is not a member; social and political trends in the republic track closely with those of its larger neighbor, Italy.

San Marino's economy relies heavily on tourism, the banking industry and the manufacture and export of ceramics, clothing, fabrics, furniture, paints, spirits, tiles, and wine. The manufacturing and financial sectors account for more than half of San Marino's GDP. The per capita level of output and standard of living are comparable to those of the most prosperous regions of Italy. The economy benefits from foreign investment due to its relatively low corporate taxes and low taxes on interest earnings. The income tax rate is also very low, about one-third the average EU level. San Marino does not issue public debt securities; when necessary, it finances deficits by drawing down central bank deposits. San Marino's economy has been contracting since 2008, largely due to weakened demand from Italy - which accounts for nearly 90% of its export market - and financial sector consolidation. Difficulties in the banking sector, the recent global economic downturn, and the sizeable decline in tax revenues have contributed to negative real GDP growth. The government has adopted measures to counter the economic downturn, including subsidized credit to businesses and is seeking to shift its growth model away from a reliance on bank and tax secrecy. San Marino continues to work towards harmonizing its fiscal laws with EU and international standards. In September 2009, the OECD removed San Marino from its list of tax havens that have yet to fully adopt global tax standards, and in 2010 San Marino signed Tax Information Exchange Agreements with most major countries. In 2013 San Marino's Government signed a Double Taxation Agreement with Italy, but a referendum on EU membership failed to reach the quorum needed to bring it to a vote.
