Prague Astronomical Clock

Located in the Old Town Square, the Prague Astronomical Clock has been around since the 15th century, though it has required repairs many times over its history.

This clock doesn't display the time of day. Rather, it's meant to be used to determine the phases of the moon and the equinoxes. On the web, recent visitors voice a mixed opinion. Some say the clock is a must-see but others note their disappointment. However, even those that felt the clock was overhyped concede that it deserves a look, especially since you're likely to be in the Old Town Square at some point during your trip anyway. One TripAdvisor user says, "I normally really enjoy historical sites, but I think this clock is overrated. Very pretty building though and it is worth seeing, but don't go out of your way to watch the clock chime."

The Old Town Square area is accessible from the Staromestská metro stop.
