The Chapel of Saint Germanus (Chapelle Saint-Germain) is one of the earliest surviving places of Christian worship in the Cotentin Peninsula. It is a small building with walls built from small pieces of shale arranged in a herringbone pattern. The chapel consists of a short nave, and transepts and a choir each formed from an identical apse with half domed roofs. This tri-lobate plan, which is unusual, is the result of a reconstruction in the 9th or 10th century on remains of a palaeo-Christian basilica which has been revealed by archaeological excavations. In the 17th century, the chapel was topped by a tower which in turn replaced an older tower structure.
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.
