Trenčín lies in western Slovakia, in the valley of the Váh River, near the border with the Czech Republic. It is the capital of the region of the same name and one of the stops on the rail line that links Bratislava with Žilina and Košice. The town has about 54,000 inhabitants and a small historic centre that can be walked in a few hours.
The castle sits on a limestone rock just above the centre. It was the seat of Matúš Čák, a noble who in the early 14th century controlled much of what is now Slovakia; tradition calls him the lord of the Váh and the Tatras. On the same rock, facing the town, there is an inscription dated 179 that records the victory of a Roman legion over the Quadi at Laugaricio, the Latin name of the place. It is one of the few written testimonies of Roman presence so far north in Central Europe.
Below the castle spreads Mierové námestie, the main square, with the Holy Trinity column, the Jesuit church of Saint Francis Xavier and the tower that used to be the town’s lower gate. A covered stairway climbs from the square up to the parish church, halfway to the castle. On the opposite side of the centre, the 1913 synagogue, with a dome and oriental motifs, has been restored and now serves as a cultural space.
About 15 km to the northeast, in a narrow valley of the Strážov Mountains, is Trenčianske Teplice, a thermal spa town with a park, 19th‑century bathhouses and a hammam with Moorish decoration.
