Bern

Bern is a city in Switzerland. Its old town sits inside a bend of a river. It has a clock tower and long covered walkways.

Bern is the federal city of Switzerland, where the country's government is based. It was founded in the 12th century on a hill surrounded by a loop of the Aare River, and its old town, with covered arcades and old fountains, is a UNESCO World Heritage Site. About 147,000 people lived in the city at the end of 2025.

Bern, the federal city of Switzerland since 1848 and capital of the canton of Bern, lies on the Swiss plateau between the Jura and the Alps. Founded in the 12th century on a hill enclosed by a loop of the Aare, its Old City keeps its medieval plan and is a World Heritage Site. The city's statistics office counted 146,867 residents at the end of 2025.

Bern is a city in Switzerland. The government of Switzerland works there.

A blue-green river curls around the old part of the city like a big letter U.

Bern is the federal city of Switzerland, the seat of the country's federal government, and the capital of the canton of Bern. It lies on the Swiss plateau, between the Jura mountains and the Alps.

The city's statistics office counted 146,867 people living in Bern at the end of 2025, and its provisional count for September 2026 was 147,494.

UNESCO describes the Old City of Berne as the federal city of Switzerland and capital of the canton of Berne, on the Swiss plateau between the Jura and the Alps. Since 1848 it has carried the role of federal city, and in the 19th century large public monuments were built to house that function.

The city's statistics office gives a definitive population of 146,867 at the end of 2025 and a provisional 147,494 for September 2026. Seen from the air, the Aare loops tightly around the old town on its narrow peninsula.

Arcades, fountains and a clock tower

In Bern's old town, people walk under long covered walkways called arcades. They stay dry when it rains.

Old fountains stand in the streets. An old tower has a big clock.

Bern's Old City has wide streets that were once used as markets, lined with arcades: covered walkways under the fronts of the houses. Some arcades date from the 15th century, and in the 16th century fountains were added along the streets. Most of the buildings are from the 18th century, made of sandy limestone.

The Zytglogge is a medieval clock tower with an astronomical clock and a carillon of bells. Close by stand Bern Minster, the city's cathedral, which was completed in the 16th century, and the Federal Palace, a federal building.

UNESCO highlights the Old City's clearly defined elements: wide streets used as markets, a regular division into narrow, deep plots, an advanced water supply system, and mostly 18th-century buildings of sandy limestone with arcades and facades carried on arches. The buildings date from many periods, including 15th-century arcades and 16th-century fountains; in the 16th century the towers and walls were also restored and the cathedral, Bern Minster, was completed.

The Zytglogge, which Wikidata describes as a medieval clock tower with an astronomical clock and carillon, stands in the old town near the Minster. Public buildings for the secular and religious authorities were always placed at the edge of the built-up area, a rule UNESCO notes was still followed in the 19th century, when the large public monuments of the federal city were built.

A planned medieval town

Long ago, people built a town on a hill. A river looped around it.

The town grew bit by bit. Much later, a famous scientist named Einstein lived there.

Bern was founded in the 12th century on a hill surrounded by the Aare River, following a careful plan. From the 12th to the 14th century, the town grew outward in stages, and its streets still follow that medieval plan.

In 1848, Bern became the federal city of Switzerland. In 1902, a young scientist named Albert Einstein moved to Bern, and that June he started work at the patent office. Living in the old town in 1905, he published the ideas we now call the special theory of relativity, including the famous equation E = mc².

UNESCO calls Bern's medieval foundation an impressive example of the High Middle Ages, built to an innovative foundation plan and expanded in several stages from the 12th to the 14th century; it ranks the town among the most significant urban planning creations in Europe. Wikidata gives the founding year as 1191.

Bern has been the federal city since 1848. Albert Einstein arrived in February 1902 and in June became a technical expert, third class, at the Federal Patent Office. From October 1903 he and Mileva Marić rented an apartment at Kramgasse 49, now the Einstein House. In 1905, his "miracle year," he published papers including "On the Electrodynamics of Moving Bodies," later called the special theory of relativity, and the paper showing that mass and energy are equivalent, E = mc².

Through the years

Trams, bridges and walking under arcades

Trams take people around Bern.

In the old town, many streets are for walking. Covered arcades line them.

Bern's trams are run by Bernmobil on narrow, meter-gauge tracks. New tram lines opened to Bümpliz and Brünnen in 2010 and to Wankdorf station in 2012.

In the old town, people walk along the wide market streets under the arcades. Bridges cross the Aare to reach the neighborhoods on the other side.

UrbanRail.net lists Bern's tram network as operated by Bernmobil on 1,000 mm meter gauge, with extensions to Bümpliz and Brünnen opened on 12 December 2010 and from Guisanplatz to Wankdorf Bahnhof on 9 December 2012.

A summary on UNESCO's page notes that most of the old streets with arcades are now walking promenades. Because the old town sits on a peninsula in a loop of the Aare, bridges link it with the districts on the far banks.

Cold winters and warm summers

Winter in Bern is cold. Nights are often below freezing.

Summer is warm and green. Rain falls in every month.

Bern has cold winters and warm summers. Measurements by MeteoSwiss, Switzerland's weather service, at its Bern-Zollikofen station average about 3 °C by day and −3 °C at night in January from 1991 to 2020. July days average about 25 °C.

Rain falls all year, adding up to about 1,020 millimeters in an average year. Summer is the wettest season, with more than 100 millimeters in each month from May to August.

MeteoSwiss's monthly measurements at Bern-Zollikofen for 1991–2020 average daily highs and lows of 3.4 °C and −2.9 °C in January and 24.6 °C and 13.0 °C in July, the warmest month; average lows are below freezing from December through February.

The monthly precipitation averages add up to about 1,022 mm. The wettest months are May (112.4 mm), August (112.2 mm) and July (108.0 mm), and the driest is February (55.5 mm), so Bern's precipitation peaks in summer.

A scientist's home and an old town for walking

You can visit the home where the scientist Albert Einstein once lived.

People walk through the old streets and look at the fountains.

On Kramgasse in the old town, Albert Einstein's former apartment is now the Einstein House. From 1903 to 1905, Einstein met with two friends, Maurice Solovine and Conrad Habicht, to talk about science and philosophy. They called their little group the Akademie Olympia.

UNESCO notes that Bern today mixes old monuments and modern buildings. In the old town, people stroll along the market streets, under the arcades and past the fountains.

Einstein's years in Bern were busy: he earned money at first by giving private lessons in physics and mathematics, which he advertised in a local newspaper; he published his first paper, on the molecular theory of heat, in 1902; he joined the Society for Natural Sciences Bern in 1903 and gave his first talk there, on electromagnetic waves. The Akademie Olympia, his discussion circle with Maurice Solovine and Conrad Habicht, ran from 1903 to 1905.

UNESCO describes the Old City as a unique example of constant renewal of its buildings while keeping the original plan, a variation of late Baroque on a High Middle Ages theme.

Bern on the map

Find Bern on the globe.

It is in Switzerland, in the middle of Europe. Look for a river that loops around the old town.

Bern is in Switzerland, in Europe. It sits on the Swiss plateau, between the Jura mountains and the Alps.

On a map of the city, the Aare River makes a tight loop. The old town fills the narrow hill inside that loop, and bridges lead across the water to newer neighborhoods. The Federal Palace, the Zytglogge clock tower, the Einstein House and Bern Minster all stand close together in the old town.

Bern lies at about 46.9° N and 7.5° E on the Swiss plateau, between the Jura and the Alps. Its Old City occupies a hill site surrounded by a loop of the Aare.

The Federal Palace, the Zytglogge, the Einstein House and Bern Minster all stand within a few hundred meters of each other on that peninsula.
