Tallinn

Tallinn is the capital and most populous city of Estonia. Located on a bay in northern Estonia, on the shore of the Gulf of Finland of the Baltic Sea, it has a population of 456,518 as of 2025 and administratively lies in Harju County. Tallinn is the main governmental, financial, industrial, and cultural centre of Estonia. It is located northwest of the country's second largest city, Tartu, however, only south of Helsinki, Finland. It is also west of Saint Petersburg, Russia, north of Riga, Latvia, and east of Stockholm, Sweden. From the 13th century until the first half of the 20th century, Tallinn was known in most of the world by variants of its other historical name, Reval.

Reval (Tallinn) received Lübeck city rights in 1248; however, the earliest evidence of human settlement in the area dates back almost 5,000 years. The medieval indigenous inhabitants of present-day Tallinn and northern Estonia were among the last "pagan" peoples in Europe to be Christianised during the papal-sanctioned Northern Crusades in the 13th century.
