Tõrva ancient fortified stronghold is situated on the gravelly
moraine ridge on the left bank of the Õhne River. In addition to
the 13-17 metres high slopes the ancient stronghold was naturally protected
by a river on one side and a marshy meadow on the other. In the southeastern
and northwestern side the access was blocked by an artificial mound. Among
other Estonian strongholds Tõrva ancient fortified stronghold strikes
the eye because of its size and the difficulty level of the building.
Thus it can be compared to Punamägi of Äntu, Sadulmägi
of Neeruti and Iru stronghold. During the archaeological excavation which
began in 1965, guided by academician Harri Moora, two levels of evolution
could be distinguished of the cultural layers of the stronghold (accordingly
from the second half of the first millennium and from the beginning of
the second millennium.
The stronghold with its surroundings is known as Tantsumägi (Dance
Hill). Under the beautiful firs an open-air stage where singing and dance
festivals are celebrated has been built. Each year a bonfire celebrating
the Midsummer Night has been lighted here. The town itself is connected
with Tantsumägi by Endla Raim, an architect from Tõrva, who
has designed the arch-bridge of tantsumägi.
