Introduction
Standing by the Old Town Hall on Zelný trh, the Brno astronomical clock is a public artwork unveiled in 2010. Shaped like a giant black bullet some six metres tall, its dark silhouette clashes theatrically with the Baroque square, and while locals mocked it at first, it has become a quirky city icon. Every day at 11 a.m. the clock releases a glass marble to one lucky onlooker, echoing the same siege legend that makes Petrov's bells ring noon an hour early.
