Volfštejn, Castle ruin and cultural monument in Třebel, Czech Republic.

Volfštejn is a castle ruin with an oval layout, dominated by a round bergfrit tower whose late Romanesque portal survives. The palace opposite the tower stands to two storeys, and a two-room building and a square tower stood by the eastern wall.

Volfštejn was founded in the first half of the 13th century; the round bergfrit with its late Romanesque portal is its oldest part. The first written mention dates from 1316, when Beneda of Volfštejn sued Dluhomil and Bedřich of Brod for murdering his father Ctibor. The lords of Volfštejn held the castle until 1460, when they moved to nearby Třebel; it was recorded as deserted in 1527.

The ruins maintain their medieval character and show how local lords once demonstrated their power over the surrounding lands. This site embodies life from an era when such fortresses were the defining symbols of regional rulers.

The ruin sits within dense forest near Třebel in the Tachov region. Visiting requires basic hiking ability since access involves unpaved paths through wooded terrain.

Dendrochronological analysis of the scaffolding found during repairs to the great tower showed that the ash wood used was felled between 1260 and 1262, dating the oldest round bergfrit with its late Romanesque portal to the mid-thirteenth century. The tower's interior was flat-ceilinged, and one of its floors was heated by a fireplace.
