Kalec Castle

Kalec Castle (Grad Kalec, originally Kalc or Kauc) is a partially ruined castle near Zagorje in Slovenia.

The castle, of which only a single tower and some sections of wall survive intact, stands on slope known as Breg, near the source of the river Pivka, at an elevation of 618 m.

Illustrated in Valvasor's 1689 Glory of the Duchy of Carniola, it was built in the mid-17th century by the noble house of Steinberg. Its later owners included the Auersperg family and the Slovene composer Miroslav Vilhar, who also died in it. The castle was abandoned by its last residents after World War I, and began falling apart.

In 1941 it hosted a meeting of the antifascist militant group TIGR.

Today the Krpan Hiking Path passes beside the ruins, which are surrounded by a copse of ancient linden trees. The path to the castle is bordered by a chestnut tree row.
