The Church of St Martin was begun in the 12th century, although most of the current structure dates from the 13th century. The church is most notable for its extreme tilt, caused as a result of a landslide. This has led to many attempts to strengthen the church and prevent its collapse, through the use of massive tie beams and buttresses.
The church is in the Gothic style, and has a chancel, nave, south porch, and western tower. A round-headed north window dates to the 12th century, and the nave roof has been dated to the late 13th or early 14th century.
In the nave of the church stands a stone cross, sometimes referred to as a wayside cross or crucifix, dated to the 11th or 12th century. In the Middle Ages the cross, which bears a rare carving of Christ on the cross, would have stood in the churchyard to be venerated by pilgrims travelling through the Black Mountains, via Llanthony Abbey, to St David's Cathedral in Pembrokeshire.
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.
