City Europe

Tallinn

Tallinn is the capital city of Estonia. It is by the sea. Its old town has stone walls, towers and red roofs.

Tallinn, the capital of Estonia, lies on a bay of the Gulf of Finland. Its walled Old Town, with towers, church spires and a town hall finished in 1404, is, says UNESCO, an exceptionally complete and well-preserved medieval trading town, and today the city is also known for its technology companies.

Tallinn, Estonia's capital on the Gulf of Finland, grew around a Danish fortress of 1219 on Toompea hill and a Hanseatic merchant town below it. Ruled by Danes, the Teutonic Order, Sweden and Russia, it became capital of independent Estonia in 1918 and again in 1991. Its Old Town has been a UNESCO World Heritage Site since 1997.

Discover Tallinn

Tallinn is the capital city of Estonia.

It is right by the sea. On a hill stands an old castle. Below it is an old town with stone walls, tall towers and red roofs.

Tallinn is the capital of Estonia, a small country in northern Europe. It lies on Tallinn Bay, part of the Gulf of Finland, an arm of the Baltic Sea. About 458,000 people lived in the city in 2024.

Tallinn has two old parts: Toompea, a hill where a castle has stood since the 1200s, and the walled Lower Town below it, where merchants once lived and traded. UNESCO calls the Old Town an exceptionally complete and well-preserved medieval trading city.

Tallinn, capital of Estonia, stands on Tallinn Bay of the Gulf of Finland. Statistics Estonia's count for 2024, cited by Wikidata, was 457,572 residents; Britannica gives 437,817 for 2021.

The historic center has two parts: Toompea hill, where the Danes built a fortress in 1219, and the walled Lower Town of merchants below. UNESCO, which inscribed the Historic Centre (Old Town) in 1997, describes it as an exceptionally complete and well-preserved example of a medieval northern European trading city, a significant center of the Hanseatic League in the 13th to 16th centuries, whose pattern of building plots survives virtually intact from the 13th and 14th centuries.

Famous places

Tallinn's old town looks like a storybook town.

It has a town hall more than 600 years old. Tall church spires point up to the sky. Thick walls with towers wrap around the old streets.

Many old buildings survive in Tallinn, or have been carefully restored. The Town Hall was completed in 1404, and the Great Guildhall, where merchants met, in 1410. The tall Gothic churches of St. Olaf and St. Nicholas rise above the rooftops.

Up on Toompea hill stand the 13th-century Toom Church and much of the old castle. Around the Lower Town run its old walls. Walking its lanes, you can still see how the town was laid out in the 1200s and 1300s.

Britannica lists the relics of Tallinn's long history that survive or have been restored, especially on Toompea and in the walled Lower Town: the 13th-century Toom Church, the Gothic Oleviste (St. Olaf's) and Niguliste (St. Nicholas's) churches, the Great Guildhall of 1410, the Town Hall completed in 1404, and much of the old castle.

UNESCO stresses how complete the ensemble is: the distribution of building plots survives virtually intact from the 13th and 14th centuries, and the town retains the salient features of a medieval northern European trading community. It also notes the exchange of ideas among Cistercians, Dominicans, the Teutonic Order and the Hanseatic towns that shaped a shared culture across northern Europe.

Danes, knights and merchants

People have lived in Tallinn for a very long time.

Long ago, soldiers built a castle on the hill. Merchants came by ship to buy and sell. Over the years, many different kings and rulers were in charge.

A fortified settlement stood here more than 2,000 years ago, and a town by the 1100s. In 1219 the Danes captured it and built a fortress on Toompea hill. Trade grew, especially after Tallinn joined the Hanseatic League, a group of trading towns, in 1285. For centuries it was often called by its German name, Reval.

Later, Tallinn was ruled by the Teutonic Knights, then Sweden, then the Russian Empire. In 1918 it became the capital of independent Estonia. After decades under Soviet rule, it became the capital again in 1991.

A fortified settlement existed on the site from the late 1st millennium BCE until the 10th–11th century CE, and a town by the 12th century. The Danes took it in 1219 and built a new fortress on Toompea; trade flourished after Tallinn joined the Hanseatic League in 1285, and in 1346 it was sold to the Teutonic Knights. Known mostly by its German name, Reval, it was a multiethnic trading town dominated by German merchants. It passed to Sweden in 1561 and to the Russian Empire when Peter I captured it in 1710.

Industry in the late 19th century drew Estonian workers from the countryside. Tallinn became capital of independent Estonia in 1918. Estonia was annexed to the Soviet Union in 1940; German forces occupied the city in 1941–44, and it was severely damaged. Many residents were deported by Soviet forces in 1940 and 1944–49, and the city's Jewish community was destroyed in World War II. Under Soviet rule the population grew from 137,792 (1934 census) to about 500,000 by the late 1980s. Tallinn became capital of the refounded Estonian republic in 1991.

Getting around Tallinn

In Tallinn you can ride a tram, a trolleybus or a bus.

In the old town, people walk along narrow stone streets. Big ships come and go from the harbor.

Tallinn's city transport includes trams, trolleybuses, which are buses powered by overhead electric wires, and city buses, and the same tickets work on all of them.

Tallinn is also a port. Ships load and unload cargo there, and fishing boats work from it too. Tallinn Airport has flights within Estonia and to other countries.

Visit Tallinn notes that the same tickets serve the city's trams, trolleybuses and city buses. Tallinn is a major commercial and fishing port, and Tallinn Airport handles both domestic and international flights.

In the Soviet period the city expanded greatly with new industries, reaching about 500,000 people by the late 1980s, while the Old Town kept its medieval plots.
