Kalec Castle 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 Pivka River, 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 Trail passes beside the ruins, which are surrounded by a copse of old linden trees. The path to the castle is bordered by a row of chestnut trees.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
