The remains of the Stegeborg castle are situated beautifully on a little island in the sea channel leading toward Söderköping. In the Middle Ages the castle was one of the most important strongholds in Sweden and also a royal palace. The oldest parts of the castle is a brick tower in the southeast corner, built in the early 13th century.
In the 18th century the castle was in bad shape and some wooden buildings were even were auctioned off. In 1938 the Swedish National Heritage Board received a small sum to clear the location of trees and repair the worst damage and raise protective roofing over certain parts. The new main building (a private residence) was completed in 1806. The herb-garden was laid out in 1988 by the present owner.
Today Stegeborg is open for tourists and the castle ruins are now also a port tavern and a marina.
References:Trenčín Castle is relatively large renovated castle, towering on a steep limestone cliff directly above the city of Trenčín. It is a dominant feature not only of Trenčín, but also of the entire Považie region. The castle is a national monument.
History of the castle cliff dates back to the Roman Empire, what is proved by the inscription on the castle cliff proclaiming the victory of Roman legion against Germans in the year 179.
Today’s castle was probably built on the hill-fort. The first proven building on the hill was the Great Moravian rotunda from the 9th century and later there was a stone residential tower, which served to protect the Kingdom of Hungary and the western border. In the late 13th century the castle became a property of Palatine Matúš Csák, who became Mr. of Váh and Tatras.
Matúš Csák of Trenčín built a tower, still known as Matthew’s, which is a dominant determinant of the whole building.
