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:The Château de Foix dominates the town of Foix. An important tourist site, it is known as a centre of the Cathars. Built on an older 7th-century fortification, the castle is known from 987. In 1002, it was mentioned in the will of Roger I, Count of Carcassonne, who bequeathed the fortress to his youngest child, Bernard. In effect, the family ruling over the region were installed here which allowed them to control access to the upper Ariège valley and to keep surveillance from this strategic point over the lower land, protected behind impregnable walls.
In 1034, the castle became capital of the County of Foix and played a decisive role in medieval military history. During the two following centuries, the castle was home to Counts with shining personalities who became the soul of the Occitan resistance during the crusade against the Albigensians.
