Tavastehus

Tavastehus, or Hämeenlinna, takes its name from the castle of Häme, a stronghold beside Lake Vanajavesi in southern Finland. Its oldest surviving parts date from around the end of the thirteenth century. The castle secured Swedish authority in Tavastia and served as the administrative centre from which the crown governed and collected revenue from the surrounding district.

In the later fourteenth and fifteenth centuries it was transformed into a richly ornamented brick castle. Vaulted halls and patterned brickwork gave the fortress a distinction rare in medieval Finland. Under Gustav Vasa it became a more closely supervised crown stronghold, and gun towers were added. An explosion in the powder store destroyed the old south tower in 1599, prompting substantial repairs. Governor-General Per Brahe established a town beside the castle in 1639. The fortress remained a landmark over the lake and the new settlement, though its former role as the residence of powerful nobles had passed. Its stone and brick walls preserved traces of the changing needs of government and defence across the centuries.
