The Alexander Nevsky cathedral is the main center for Russian Orthodoxy in Estonia. Built in 1900, the design was by the St Petersburg architect Mikhail Preobrzhenski and features the classical onion domes typical of Russian churches. Nevsky was the Russian hero who defeated the vastly superior forces of the Tuetonic nights in the 13th century. According to local legends, the structural damage the cathedral has suffered this century results from it's having been built on the grave of the local hero Kalevipoeg.
