The "mother" of the Lutheran Church of Finland, this Gothic cathedral from the 1200s is the greatest medieval monument in the country. Built on the banks of the Aura River, this imposing brick-built structure is dedicated to the Virgin Mary and Finland's first bishop, St. Henrik. Buried in the vaults are bishops, warlords, and even one queen, Karin Månsdotter, wife of King Erik XIV of Sweden.

Since its partial destruction by fire in 1827, the cathedral has been completely restored. The massive west tower rises to a height of 102m (335 ft.), the work of C. L. Engel, the famous German architect. Engel also designed the pulpit.

The cathedral contains no grand treasures, although there are beautiful stained-glass windows. Found in the South Gallery is the finest cathedral museum in Finland, the Tuomiokirkkomuseo, with its collection of relics and liturgical artifacts dating from the Middle Ages. The medieval wood sculptures are most impressive, as are the models depicting different stages of the Dom's construction. We like to come here on a Tuesday evening when the cathedral features live music.
