Saaremaa Regional Museum

Housed in the majestic Kuressaare Castle is the Saaremaa Regional Museum. On the ground floor look for the hüpokaust (hypocaust) on the southwestern side - a furnace that fuelled a medieval central heating system. According to legend, condemned prisoners were dispatched through a small room without a floor near the bishop's chamber, to be received by hungry lions.

Legends also tell of the body of a knight found when a room previously sealed with bricks was uncovered in the 18th century. It is said that, upon discovery, the knight's body dissolved into dust, which has given rise to varying accounts of how the unfortunate captive met his tragic fate.
