The 16th-century Renaissance building was once home to the office of the Polish astronomer and city councillor Johann Hevelius, whose statue can be found in the park in front of the building. The former headquarters of the Council of Gdansk, the Old Town Hall served as the headquarters of the Soviet Army during the dying days of WWII, probably because it was practically the only building left standing in the city at the time. Today the building is open to the public and has become the focus of much creativity. There's also a cellar restaurant, and a good bookshop on the ground floor.
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.
