Burg Friedland, Medieval castle in Friedland, Brandenburg, Germany.

Burg Friedland is a castle on a raised mound in Friedland, Brandenburg, surrounded by a zwinger with small defensive rondelles at its corners and a rectangular bastion on the west side. The east side retains the three-storey residential tower and the 1658 plastered half-timbered building between the towers, while the south side has a gatehouse with three Gothic window openings and a causeway that replaced the drawbridge in 1758.

The town of Friedland was first recorded on 3 August 1301 as castrum et oppidum Vredeburch, but the castle itself appears in documents only in 1336. In 1518 the Johanniterordensmeister Veit von Thümen acquired the town, castle and fourteen villages. A town fire in 1623 destroyed the castle down to its foundations, leaving only the two-metre-thick perimeter walls and cellar barrel vaults.

The castle housed Friedland's town library from 12 November 1975, and the Rittersaal was converted into a concert room in 1979. Since summer 2005 the castle has hosted alternating summer theatre with Beeskow and Storkow, and its rooms hold changing thematic exhibitions. A local legend tells of a White Lady said to haunt the walls on full-moon nights.

A children's playground is located in front of the castle grounds, making it convenient for families visiting the site. Numerous hiking trails wind through the surrounding landscape of Lower Lusatia, giving visitors options to explore the region at their own pace.

A fire in 1623 caused severe damage to the castle, but it was reconstructed using new building techniques and given a half-timber structure. The rebuilding completed by 1658 demonstrates how such fires led builders to adopt different construction approaches.
