The belfry of Namur, also called Saint-Jacob's Tower was constructed in 1388 as part of the city wall. It was remodeled as a belfry in 1746. It is one of the 56 belfries of Belgium and France classified as the World Heritage Site of the UNESCO.
In the beginning, one of the clocks of the Saint-Pierre-au-Château church served as belfry for the citizens of Namur, which is to indicate the time and to announce events in the city. After the destruction of the church, burned down during the siege of Namur in 1745, the Tour Saint-Jacques, the oldest of the three towers of the medieval city walls, became the city belfry. The Tour Saint-Jacques protected one of the city gates. Its bancloque (belfry clock) gave the signal for the opening and closure of the external city gates (from 1570 on).
At the beginning of the 18th century, the city wall was demolished but the Tour Saint-Jacques was preserved, restored and its clock was covered by an octagonal structure. This entire part was lifted upon a clock bulb. The Tour Saint-Jacques became Namur's city belfry in 1746.
References:Ogrodzieniec Castle is a ruined medieval castle originally built in the 14th–15th century by the W³odkowie Sulimczycy family. Established in the early 12th century, during the reign of Boles³aw III Wrymouth, the first stronghold was razed by the Tatars in 1241. In the mid-14th century a new gothic castle was built here to accommodate the Sulimczycy family. Surrounded by three high rocks, the castle was well integrated into the area. The defensive walls were built to close the circuit formed by the rocks, and a narrow opening between two of the rocks served as an entrance.
In 1470 the castle and lands were bought by the wealthy Cracovian townsmen, Ibram and Piotr Salomon. Then, Ogrodzieniec became the property of Jan Feliks Rzeszowski, the rector of Przemy¶l and the canon of Cracow. The owners of the castle about that time were also Jan and Andrzej Rzeszowskis, and later Pilecki and Che³miñski families. In 1523 the castle was bought by Jan Boner.
