The most historic dominant of the city is Trenčín castle – Trenčiansky hrad. Equally worth is visiting the many galleries, museums and churches in the city. In the close neighbourhood of Trenčín you can visit Beckov castle and the castle in Čachtice, renowned for legends of countess Báthory.
The Castle of Trenčín built on top of a steep rock is undoubtedly the dominant of the town Trenčín and the region of Považie. The Castle, which is along with those of Spiš and Devín one of the biggest in Europe, is the National Cultural Monument.
It was the royal castle from the 11th century. The bulky fortifying system is the result of progressive perfection of an important boundary fort, later seat of the county.
It had an important role above all in time of Turkish attacks. It was property of several aristocratic families while Matúš Čák of Trenčín was the best known owner of the Castle. He also owned other Slovak castles, which won him the nickname of the Lord of the Váh and the Tatras. As the owners changed, the functions of the castle either changed or multiplied. The castle area, which is part of the Trenčianske múzeum consists of a set of palaces.
