14539 Clocke Roeland           Discovered 1997 Sept. 10 by T. Pauwels at Uccle.
Klokke Roeland (or `Clocke Roeland', using the historic spelling) is the storm bell that is the symbol of the independent spirit of the city of Ghent. The name in fact refers to three successive bells, cast in 1314, 1660 and 1948 respectively.
