Tallinn is the oldest capital city in Northern Europe. The city was known as Reval from the 13th century until 1917 and again during the Nazi invasion of Estonia from 1941 to 1944.
Up to the 13th century the Scandinavians and Henry of Livonia in his chronicle called the town Lindanisa: Lyndanisse in Danish. Lindanäs in Swedish, also mentioned as Ledenets in Old East Slavic. According to some theories the name derived from mythical Linda, the wife of Kalev and the mother of Kalevipoeg. who in an Estonian legend carried rocks to her husband's grave that formed the Toompea hill.
It has been also suggested that in the context the meaning of linda in the archaic Estonian language, that is similar to lidna in Votic, had the same meaning as linna or linn later on meaning a castle or town in English. According to the suggestion nisa would have had the same meaning as niemi (meaning peninsula in English) in an old Finnish form of the name Kesoniemi.
