St Mary's Church dates from the twelfth century. At this church the Rev. Legh Richmond is thought to have originated the now globally popular idea of using boards with movable numbers to indicate hymn numbers during church services. The 13th-century tower is of a very unusual style in that it is built on four piers at the entrance to the church. This is one of only four in examples in Britain. The tower contains a ring of 8 bells which the heaviest weighs 10.5cwt in the key of G. The oldest bell was made in 1594.
The current church building has aspects dating from the late 12th century onward, with the majority of the present building resulting from the alterations of the 14th and 15th centuries. The Oglander Chapel on the eastern end of the south aisle is the resting place of members of that family and includes two elaborately carved and painted wooden effigies of knights placed upon two of the tombs. Whilst installed by the family itself, their appearance does not represent the accurate historical dress of the time for the family members in the tombs beneath. In the north aisle there are funerary hatchments of the Oglander family on the walls, and two fonts from the 13th and 15th centuries.
The churchyard contains the Commonwealth war graves of four British Army soldiers of World War I.
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.
