St. Nicholas Church is a large, cruciform town church set on Place Dalton at the heart of the lower town which clusters below the walls of the citadel. Due to the destruction of the French Revolution, WWI and WWII it is the most significant surviving medieval building in the town.
The church is first mentioned in 1208 as a foundation of the Abbey of Notre-Dame within the citadel, a relationship which existed into the 16th century. About this time, the silting up of one of the channels caused the centre of the town to move southwards, and St Nicholas took over from St Peter as the main town church.
The vaulted roofs in the nave and transepts were installed in the 17th century, but their weight caused the walls to crack, and as part of the rebuilding the nave was widened and lengthened, a response to the doubling in population of the lower town that century.
All the glass was destroyed during the liberation, and has so far been replaced in the lower stories with some splendid 1980s abstract designs.
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.
