In the 2nd century AD, the city-sanctuary of Gisacum extended near Saint-Aubin, which was gradually abandoned until disappearing in 5th century. In the 1801 archaeological excavations uncovered this important Gallo-Roman site; but in reality at the time the town covered an area of 250 ha. The interpretation centre has a permanent exhibition tracing the history of Gisacum, and the archaeological garden offers an original development of the thermal baths, which helps to visualise the disappeared monuments, in a pleasant landscape setting.
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.
