Constructed between 1406 and 1410, Amiens' massive square belfry has a mid-18th-century top reaching 52m, which was rebuilt after it was damaged in 1940 by German bombing. The tourist office runs two guided tours per month, one including a cathedral tour, plus night-time visits in July and August – check the website and reserve well ahead.
Today the belfry is part of the UNESCO as a World Heritage Site The Belfries of Belgium and France, a group of 56 historical buildings.
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.
