If you ever wanted to see the famous Eiffel Tower, but Paris is out of your budget, go to Prague and visit Petrin Lookout Tower. Prague has been nicknamed the “city of a thousand spires” for good reason: as you glance over its 1,100-year-old skyline, you’ll be rewarded with splendid views of lovely domed churches and soaring old towers that combine to make Prague one of the world’s architectural gems.
