There was originally a strong fortified castle Beritzholm few hundred meters from the present Bjärsjölagård Castle. It was built by Valdemar Atterdag in the 1300s and demolished in 1526. Peter Julius Coyet bought the estate from Crown in 1720. There was a lime factory in the beginning of the 19th century and two ovens still remain. The current main building was built in Rococo style in 1766 and the southern wing in 1812. The newer addition on the estate, was built in Romantic, German style in 1849-50, on a hill just south of the old castle. It is a three-story building flanked by two square towers. Today Bjärsjölagård is a hotel.
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.
