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 Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
