The ruins of the castle on the summit of Góra Zamkowa (Castle Mountain)
on the fringes of the town of Wleń
, in the foothills of the Western Sudetes
. The mountain has been designated a nature reserve in order to protect its flora. What is left from the castle – until 1945 called Hedwigsburg by the locals – is its oldest part built by Prince Henryk I Brodaty
in the first half of the 13th c.
