Wegelnburg, Rock castle ruins in Palatinate Forest, Germany.

Wegelnburg is a rock castle ruin in the Palatinate Forest standing at about 570 meters elevation with three wards that are still partly visible. The castle features preserved stone walls, gateways, and foundation remnants that show its original layout.

Wegelnburg was first mentioned in 1247, when Konrad IV granted it as a fief to Friedrich III von Leiningen; it had previously been held by B. de Waeglenburc. In 1330 it was pawned to the Palatinate and in 1417 passed by barter to Pfalz-Zweibrücken. Imperial mercenaries took and damaged it during the Thirty Years' War, and French troops destroyed and slighted it in 1679 under the Peace of Nijmegen.

The castle shows how builders carved staircases, gateways, and rooms directly from the sandstone to create a fortification. This method of working with natural rock was common for defensive structures in this region and made the castle blend with its surroundings.

The ruin is reachable by hiking trails starting from nearby villages or from Fleckenstein castle, with walks of less than an hour. Wear sturdy shoes and dress for changing weather since the terrain is rocky and exposed.

The castle's two water shafts are cut straight into the rock: the larger opening measures about 2.15 m across and is free to a depth of roughly 8.5 m before rubble fills it, while a second shaft only 90 cm wide drops about 4 m. Both show how thoroughly the site was supplied with water.
