Ruine Lichtenfels, Medieval castle ruins in Zwettl, Austria
Ruine Lichtenfels is a medieval castle on a peninsula in Lake Ottenstein, surrounded by the Kamp River's waters. The remains include partially preserved stone walls and foundations, with the old chapel structure still visible.
The castle was founded in 1159 when Duke Heinrich II granted the estate to his vassal Hartung von Rauhenegg. It later became an important stronghold for the monasteries in the region.
The name Lichtenfels means 'field of light,' referring to its exposed position on the peninsula. Today visitors can see from the dam how the ruins sit prominently above the water, still suggesting the spiritual importance this place once held.
The ruins are best observed from the dam bridge, which offers an unrestricted view of the structure. The area around the lake has swimming facilities and camping grounds that complement a visit.
An old chapel on the site was dedicated to Saint Paul and attracted pilgrims until the 20th century. This religious use made the location more than just a fortress, but also a destination for the faithful.
