Lõhavere Lembitu linnamägi is an ancient Estonian hill fort in Viljandi County, named after the legendary chieftain Lembitu who occupied the stronghold during the Late Iron Age. Founded at the end of the 12th century, the fort was built on a moraine hill rising 8-10 metres above the terrain, featuring a man-made sand wall originally reinforced by a 2.5-metre timber palisade and protective wooden structures. One of Estonia's most thoroughly studied archaeological sites, nearly two-thirds of the stronghold has been excavated since major investigations began in the late 19th century. Today the site stands as a registered state archaeological monument and recreation area.
