Astronomical Clock (Orloj)

The Astronomical Clock (Orloj) on Prague's Old Town Hall is a medieval mechanical marvel and the third-oldest astronomical clock in the world, dating to 1410. On each hour from 9am to 11pm, the clock comes alive as Death rings a bell, windows open to reveal the Apostles, a rooster crows, and figures of vanity, greed, and lust shake their heads. The clock face displays the current time, the positions of the sun and moon, astronomical cycles, and the time of sunrise and sunset — all simultaneously.
