Ruins of a Livonian Order castle tower atop a steep hill alongside the Pärnu-Valga highway in Helme. The castle changed hands from Germans to Russians and Lithuanians to Swedes who eventually destroyed it in 1658. The spring at the foot of the hill is believed to cure seven diseases.
North from the ruins are Helme caves which local people have also called the Hell. The village also has a local history museum.
