Lieper Burg is a castle rampart in the municipality of Thelkow in the district of Rostock, Mecklenburg-Vorpommern. It is an early Slavic hilltop castle from the 8th century.
The castle ( 54°03'26.5 "N 12°33'10.6 "E ) stands on a spur-like promontory twenty meters above the Recknitz valley. The inner surface of Lieper Castle is relatively large, compared to many other Slavic castle complexes in northern Germany. The diameter of the inner surface is over a hundred meters. The castle rampart was heaped up from sand on the earth surface and in the core it was bordered by stone packs. It has a width of 13 meters at the base. Deep ditches additionally protected the complex.
Lieper Burg is located in a forest in the area of the southern upper slope of the Recknitz valley, not far from the village Liepen and belongs to the LSG Lieper Burg. The castle lake lying in the same forest is named after Lieper Burg and invites you to linger. Two large erratic blocks were pushed here by the ice age and are worth seeing. Not far to the south is the Teufelssee nature reserve near Thelkow.
