KIHELKONNA METSKOND 531, Nõmpa küla, Saaremaa vald, Saare maakond
Ring fort is situated away from villages in the forest, on the sand dunes that are partly surrounded by swamps. The place is very well protected by nature: on the North-West runs small creek, on the East and South-East there are 3-4 m high sand dunes. During construction of ring fort the dunes were connected so that a oval ring embankment was created.
Interesting to know: From construction point of view the strongest fort on Saaremaa. Lihulinn has the biggest yard area on Saaremaa - app. 18 000 m². At the inner side of embankment foot were found half-burned beam ends and coal.
