The Bottroper Glockenspiel is a glockenspiel consisting of 25 bronze bells on the facade of the Hansastrasse 10 in Bottrop. 1957 began the master watchmaker and goldsmith Gerd Triffterer (* 1927 in Aschendorff / Emsland, † 2009 in Bottrop) to plan the carillon until it was inaugurated in November 1963. The 25 bronze bells with a total weight of 1085 kilograms were cast by a Dutch specialty company. In 2007, the carillon and clockworks were restored and the steel suspensions for the bells on the facade were renewed. The glockenspiel system can be played by hand on a specially built organ as well as with paper or plastic rollers, which can sound with a hole pattern the sounds. For the Glockenspiel there are 17 roles with Jahreszeitenliedern, Schützenfest- and Weihnachtsliedern up to the general folk song. In 1982, a miner's figure was put on the biggest bell as a sign of the history of the region. In addition, five clocks are also part of the carillon: a mother clock with Central European time and four world time clocks that show the times of New York City, Tokyo, Sydney and Cape Town. Everyone has their own clockwork. The "watch ensemble" was supplemented in 1994 by the construction of the outdoor stand clock.
