The 47-metre-tall belfry is standing in the center of Béthune. The Belgian border can be seen from the top. The chime of the belfry is composed of thirty-six bells. A belfry has stood on the site since 1346. The current belfry plays melodies every 15 minutes, including the ch'ti (regional patois) children's lullaby min p'tit quinquin (my little darling). In 2005, the belfry was inscribed on the UNESCO World Heritage List as part of the Belfries of Belgium and France site, because of its architecture and testimony to the rise of municipal power in Europe.
Křivoklát Castle was founded in the 12th century, belonging to the kings of Bohemia. During the reign of Přemysl Otakar II a large, monumental royal castle was built, later rebuilt by king Václav IV and later enlarged by king Vladislav of Jagellon.
The castle was damaged by fire several times. It was turned into a harsh prison and the building slowly deteriorated. During the 19th century, the family of Fürstenberg became the owners of the castle and had it reconstructed after a fire in 1826.
Today the castle serves as a museum, tourist destination and place for theatrical exhibitions. Collections of hunting weapons, Gothic paintings and books are stored there.
