Slovenia

Slovenia is a small country in Europe. It has tall mountains, deep caves, green forests and a little bit of seaside.

Slovenia is a small country in central Europe where the Alps meet the Mediterranean. Forests cover much of the land, the Karst region is full of caves and underground rivers, and about 2.1 million people lived there in 2026.

Slovenia is a small but topographically diverse central European state that takes in parts of the Alps, the karstic Dinaric Alps, the Pannonian lowlands and a short Adriatic coast; the word karst itself comes from its Kras region. Part of Yugoslavia for most of the 20th century, it became independent in 1991, and its statistics office counted 2,136,385 residents on 1 April 2026.

Slovenia is a small country in Europe.

It has high mountains and deep caves. It has thick green forests. It has a short coast by the sea. The capital city is called Ljubljana.

Slovenia is a small country in central Europe. In this small country there are high Alpine peaks, caves and underground rivers, fertile river valleys in the east and a short Mediterranean coast in the southwest. Forests cover about three-fifths of the land.

Its capital, Ljubljana, sits near the middle of the country. About 2.1 million people lived in Slovenia in 2026, and most of them speak Slovene, a South Slavic language. Slovenia became independent in 1991 and joined the European Union in 2004.

Britannica describes Slovenia as small but topographically diverse, made up of portions of four major European landscapes: the Alps, the karstic Dinaric Alps, the Pannonian and Danubian lowlands and hills, and the Mediterranean coast. The country is mostly elevated; the only major flat area is in the northeast, and tectonic fault lines cross it (Ljubljana suffered a devastating earthquake in 1895). Easily crossed mountain passes, now replaced by tunnels, long made it a route between the Mediterranean and transalpine Europe.

The Statistical Office of the Republic of Slovenia (SURS) counted 2,136,385 residents on 1 April 2026, of whom 10.7 percent were foreign citizens. Slovenia covers 20,271 square kilometers. It was largely ruled by the Habsburgs for most of its history and was part of Yugoslavia for most of the 20th century; it seceded in 1991 and joined NATO and the European Union in 2004.

Cities and famous places

Ljubljana is the capital of Slovenia.

A castle stands on a green hill above the old town. A river runs through the city. Not far away are lakes, and caves with underground rivers.

Ljubljana, the capital, is Slovenia's most important city, with a castle on a wooded hill above its old town. Between the two world wars, the architect Jože Plečnik reshaped the city with a green promenade and a riverside walk with bridges along the Ljubljanica River, and UNESCO listed his work in 2021.

Beneath Mount Triglav, in the Alps, lie Lake Bohinj and Lake Bled. In the southwest, the Škocjan Caves hold a huge underground canyon carved by the Reka River. Koper, on the short coast, is Slovenia's main port, and Maribor is a city on the Drava River in the east.

Ljubljana, in the Ljubljana basin on the southern edge of Gorenjska, is the capital and most important city. UNESCO inscribed "The works of Jože Plečnik in Ljubljana" in 2021: between the two world wars Plečnik (1872–1957) designed a land axis, the Green Promenade, and a water axis of embankments and bridges along the Ljubljanica River, connecting the historic center with the suburbs as the town grew from a peripheral town of the Austro-Hungarian Empire into a national capital.

The Škocjan Caves, inscribed in 1986, protect 413 hectares on the Kras Plateau, where the Reka River disappears underground into a canyon about 2 km long, up to some 150 m high and in places more than 120 m wide; its Martel Chamber exceeds two million cubic meters. Idrija, inscribed in 2012 with Almadén in Spain, was one of the two largest mercury mines in the world until recent times. Koper, just south of Trieste, is Slovenia's major port on a coast only 47 km long.

Alps, karst and coast

Slovenia has very tall mountains called the Alps.

The tallest one is Triglav. In another part, rain sinks into the ground. It makes caves and rivers under the ground.

About two-fifths of Slovenia is Alpine mountains. The highest peak, Triglav, is 2,864 meters tall, in the Julian Alps. Triglav National Park, Slovenia's only national park, protects the mountains around it.

In the southwest is the Kras, or Karst, a limestone region dotted with caves and underground rivers. It gave its name to all landscapes like it: scientists everywhere call them karst. Water is scarce there. In the east, the valleys of the Sava, Drava and Mura rivers have fertile farmland, and most of Slovenia's rivers flow toward the Danube.

Slovenia has four main physiographic regions. The Alpine region, about two-fifths of the country, includes the Kamnik-Savinja Alps, the Karavanke and the Julian Alps with Triglav, 2,864 m (Slovenia's Surveying and Mapping Authority refined the figure to 2,863.65 m in 2016). The Kras, a spur of the Dinaric Alps covering one-fourth of the land, is dotted with caves and underground rivers; scientific study of karst began here in the 18th century. Subpannonia, a fertile fifth in the east, holds the Sava, Drava and Mura valleys, and Primorska, barely one-twelfth, includes Slovenia's part of Istria.

Most rivers drain toward the Danube; the Soča rises beneath Triglav and reaches the Gulf of Venice in Italy. Istria is transitional between Mediterranean and moderate continental climates, with the cold bora wind; central and northern Slovenia have a cool-summer continental climate and the east has warmer summers. Below freezing is frequent from November to February, but snow cover has become less frequent. Forests, noted for their mushrooms, cover about three-fifths of the country, and Triglav National Park, first protected in 1924, covers 840 km², 4 percent of Slovenia.

Animals of Slovenia

Brown bears live in Slovenia.

Chamois and ibex live high in the mountains. A pale salamander called the olm lives in dark caves. It has no eyes you can see.

Slovenia is home to brown bears, wild boar and red, fallow and roe deer, and the lynx has come back. In Triglav National Park, chamois live on rocky ground above the trees in summer, and Alpine ibex were brought back starting in 1964. Alpine marmots, which had died out in the area long ago, were returned at the end of the 20th century.

Deep in the caves lives the olm, a pale salamander 25 to 30 centimeters long. It is the only animal with a backbone in Europe that lives only in caves, and it can live for up to 100 years.

Britannica lists protected species including the reintroduced but still rare ibex, the European brown bear, the chamois, the wild boar and red, fallow and roe deer, and notes that the lynx has reappeared; the Subpannonian lowlands suit migratory fowl, and the Soča is known for trout and grayling. Triglav National Park records about 7,000 species. There, chamois keep to open rocky terrain above the tree line in summer and move into forest in winter, ibex have been reintroduced since 1964 (all of Europe's ibex descend from the Gran Paradiso population in Italy), and Alpine marmots, extinct in the region since the end of the Ice Age, were reintroduced in the late 20th century.

The olm (Proteus anguinus), endemic to the Dinaric karst, is 25–30 cm long and, according to Slovenia's government information site, the only European vertebrate strictly bound to caves. Its eyes are vestigial and covered by skin, it keeps larval gills, it eats crustaceans, worms and snails, and it can live up to a hundred years. In 2016 an olm laid 64 eggs in Postojna Cave, and 22 young hatched.

People, languages and food

About 2.1 million people lived in Slovenia in 2026.

Most people speak Slovene. Some people speak Italian or Hungarian too. Many families keep bees and make honey.

About 2.1 million people lived in Slovenia in 2026; early in the 2000s, only about half of the people lived in towns and cities. Most speak Slovene, a South Slavic language with a special feature: besides words for one thing and many things, it has a form for exactly two. Italian and Hungarian are also spoken in the areas where those communities live.

Beekeeping is a way of life for many families in Slovenia. Beekeepers care for about 200,000 bee colonies of the Carniolan bee, kept mostly in wooden bee houses near their homes, and many hives carry painted panels, a traditional art.

Britannica estimates that about nine-tenths of Slovenia's people are ethnically Slovene, descendants of Slavic settlers who arrived in the 6th century CE; Italians (mainly in Istria) and Hungarians (mainly in Prekmurje) are the two main ethnic minorities, and Roma communities are long established in the northeast and south. Many people also came from other former Yugoslav republics. SURS counted 10.7 percent foreign citizens among residents on 1 April 2026. Slovene, the official language, is one of the few languages to keep the dual number of Proto-Indo-European, used for exactly two persons or things. In the early 21st century about three-fifths of Slovenes were Roman Catholic, with smaller Muslim, Orthodox and Protestant communities.

In 2022 UNESCO added "Beekeeping in Slovenia, a way of life" to its Intangible Cultural Heritage list. The only bee kept in Slovenia is the Carniolan bee, in around 200,000 colonies, mostly in wooden apiaries near beekeepers' homes; bee products are used for food and traditional medicine, and hives carry characteristic painted panels.

A long history

People have lived in Slovenia for a very long time.

Long ago, other countries ruled it. Then it was part of a bigger country called Yugoslavia. In 1991 Slovenia became its own country.

Slavic people settled in this land in the 500s. About the year 1000, someone wrote down confessions and sermons in the Freising Manuscripts, the oldest known writing in an early form of Slovene. From the late 1200s and the 1300s, most of the Slovene lands came under the Habsburg family of Austria, who ruled them for hundreds of years.

In the 1500s, scholars printed a Slovene translation of the Bible, and in 1843 the first Slovene-language newspaper appeared in Ljubljana. After 1918, Slovenia became part of a new kingdom that was later called Yugoslavia. In 1991 Slovenia became independent, and in 2004 it joined the European Union.

The ancestors of most Slovenes, Slavs probably from between the Black Sea and the Carpathians, settled in the 6th century CE; Christianity was accepted in the 8th century. The Freising Manuscripts of about 1000 CE are the earliest known document in what became Slovene. Styria passed to the Habsburgs after 1278, and Carinthia and Carniola in 1335, beginning centuries of Habsburg rule. Protestant scholars such as Primož Trubar printed in Slovene in the 16th century; from 1809 to 1814 much of the land formed Napoleon's Illyrian Provinces, which favored Slovene as an official language, and Jernej Kopitar published the first Slovene grammar in 1808.

After Austria-Hungary collapsed in 1918, Slovenia joined the Kingdom of Serbs, Croats and Slovenes (Yugoslavia from 1929). During World War II it was divided among Germany, Italy and Hungary, and after the war it became a republic of communist Yugoslavia. In December 1990 more than 90 percent of voters backed independence in a referendum, and Slovenia seceded on June 25, 1991; Britannica records a short conflict, known in Slovenia as the Ten-Day War, after which the last Yugoslav soldier left on October 25, 1991. A democratic constitution followed on December 23, 1991. Slovenia joined NATO and the EU in 2004 and adopted the euro in 2007.

Slovenia on the map

Find Slovenia on the globe.

It is in Europe, near the top of the Adriatic Sea. It has four neighbor countries. Its piece of coast is very short.

Slovenia is in central Europe, at the northern end of the Adriatic Sea. It has four neighbors: Austria to the north, Hungary to the northeast, Croatia to the east and south, and Italy to the west.

Its border with Croatia is about 670 kilometers long. In the southwest, Slovenia has a short strip of coast, only 47 kilometers long, on the Gulf of Venice, with the port of Koper.

Slovenia is bordered by Austria to the north, Hungary to the far northeast, Croatia to the east, southeast and south along a border about 670 km long, and Italy's Friuli-Venezia Giulia region to the west. To the southwest it adjoins the Italian port of Trieste and occupies part of the Istrian Peninsula, with a 47 km coastline on the Gulf of Venice; Koper is its major port.

The Sava rises in the Julian Alps and flows past Ljubljana toward Croatia, its valley carrying the railway to Zagreb and Belgrade; the Drava and Mura enter from Austria and meet in Croatia, and all three reach the Danube. Britannica notes that the largest Slovene communities outside the country live in Italy's Friuli-Venezia Giulia, Austria's Carinthia and Styria, and Hungary's Vas and Zala counties.
