Baltic startup capital with five-thousand-year roots
Tallinn, Estonia's capital on a Gulf of Finland bay, counted 452,563 residents as of 2026. Settlement traces nearly five thousand years; Lübeck rights arrived in 1248 for medieval Reval after Denmark's Valdemar II seized the site in 1219.
A small community of hunters and fishers left the first traces in today's centre, with comb ceramic pottery from about 3000 BCE and corded ware from roughly 2500 BCE. A fortress rose on Toompea hill around 1050. The Icelandic Njál's saga calls the area Rafala, Henry of Livonia wrote of Lindanisa around 1229, and after the Danish conquest Scandinavians and Germans knew the town as Reval. The Estonian name is usually read as Taani-linna, Danish castle, after the fort the invaders built on the site of an Estonian stronghold following the battle of Lyndanisse. Reval faded from international use only after independence in 1918.
Its harbour sat on the trade route between Novgorod and western Europe, which drew crusading Danes and the Teutonic Order in the early 13th century, when Christianity was imposed by force on some of Europe's last pagans. Reval joined the Hanseatic League in 1285 as its northernmost member, and Denmark sold it to the Teutonic Order in 1346. The Old Thomas weather vane went up on the town hall spire in 1530, the city turned Lutheran, and in 1561 it passed to Sweden. Plague-ravaged Tallinn surrendered to Russia in 1710 during the Great Northern War, though local institutions kept wide autonomy until 1889.
Estonia declared independence in Tallinn on 24 February 1918. Soviet annexation followed in 1940, German occupation from 1941 to 1944, and Soviet bombing damaged the city. The 1980 Olympic sailing events at Pirita brought the TV Tower and other new buildings. Independence was restored on 20 August 1991; UNESCO inscribed the Old Town, among Europe's best-preserved medieval centres, in 1997; Eurovision came to town in 2002, was European Capital of Culture in 2011 and won the European Green Capital Award for 2023.
Tallinn lies just 80 kilometres south of Helsinki. In 2012 it had Europe's highest number of startups per head among capitals and big cities, and it is where Skype and Bolt began. It also hosts the EU's IT agency and NATO's cyber defence centre. Lake Ülemiste supplies most of its drinking water.
