Saint Nicholas Church is a small Gothic church where Jean Calvin led services and preached in 1538. The Church no longer functions as a parish church, today it is used by a Charismatic group called 'Renouveau Saint Nicholas'.
The church was built between 1387 and 1454 on the site of an earlier church dedicated to Mary Magdalene. This earlier church, which dated from 1182, was founded by the Knight Walther Spender and had been built on the site of a small Roman fort. The tower with its tapering spire was erected in 1585 . The interior was remodeled during the 17th Century. The façade and the sacristy, which date from 1905, are by Émile Salomon, the architect of the Temple Neuf.
The interior contains remains of 15th Century frescoes. The 1707 organ of the brothers Andreas and Gottfried Silbermann was dismantled in 1967.
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.
