Astronomical Clock

The Brno astronomical clock is a black stone monument in Brno, Czech Republic. It is situated at Náměstí Svobody, the main square in the Brno City Centre. The monument was proposed by the mayor of Brno, Roman Onderka, and it was created by Oldřich Rujbr and Petr Kameník. Every day at 11:00 AM, the clock releases a glass marble, which spectators can catch from one of four openings in the monument and take with them as a souvenir.
