The place of the Tarvastu castle has been an ancient fortified stronghold. A medieval Order castle, surrounded by a moat, was built at the River Tarvastu, during the 14th century, and exploded in 1596. In the yard of the front stronghold, there is a light-coloured classicist chapel, founded in 1825, to be burial place of the v. Mensenkampff's family. The suspension bridge, which connected the hill of the front fort with the other bank, is now in the Viljandi Castle Hills.
