The Dalaborg Castle was built in 1304 by dukes Erik and Valdemar (the sons of Magnus Ladulås) during the war against the king Birger. The castle was destroyed in 1434 in the so-called Engelbrekt uprising. The Queen Margareta, regent of Norway and Denmark, was named also as a regent of Sweden in Dalaborg in 1388.
Today the moat, ramparts, a terrace and the cellar of a blockhouse remain of castle. A model of Dalaborg before it was destroyed can be seen at Mellerud Museum.
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.
