The Church of the Holy Cross (Église Sainte-Croix) was formerly the church of a Benedictine abbey founded in the 7th century, and was built in the late 11th-early 12th centuries. The façade is in the Romanesque architectural style.
The church has a nave and four aisles, a transept with apses on each arm, and a polygonal apse. The nave is 39 m long, while the apse is 15.30 m high. Its organ dates from the 18th century.
In the 19th century, the church was renovated by Paul Abadie. The former Benedictine abbey now houses the École des beaux-arts de Bordeaux.
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.
