The greystone church in Parainen was built in the 15th century (probably in 1440-1460) and is dedicated to St. Simon. The western part of the Agricola-chapel is the eldest component of the church, today a museum. On the churchyard is located the chapel of bishop Tengström, Finland's first archbishop (erected in 1819). The interior of the church is covered with several coat of arms. The rarest one is dedicated to pope Innocentius III.
National Board of Antiquities has named the church and the surrounding Vanha Malmi old town as national built heritage.
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.
