Prague Astronomical Clock Tower

An elevator now facilitates the climb atop this iconic tower, in the middle of the Old Town Square. The top is not for those with vertigo: the railings are low, the path that snakes around the outside is narrow and there’s seemingly no limit as to how many visitors are allowed. Time your trip wisely (lunchtime when everyone else is in the restaurants is a good time, as is evening just before they close); the 360-degree views are worth the wait and make for a wonderful way to situate yourself in the city.
