Adria Cathedral (Duomo di Adria) replaced the much older former cathedral nearby, dedicated to Saint John, which continues in use as a parish church. The new cathedral, dedicated to Saints Peter and Paul, was built in the early 19th century over a 14th-century church. When works were undertaken in 1830 to investigate the stability of the foundations, a Byzantine crypt and frescoes were discovered.
The cathedral also contains a Byzantine bas relief of the 6th century, a Byzantine altar and crucifix, and in the sacristy some magnificently carved cupboards by Jacopo Piazzetta from the Charity School of Venice.
Behind the building a replica of the Grotto of Lourdes was constructed in the 1930s, which still attracts many visitors.
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.
