The Petřín Lookout Tower in Prague is a cool steel tower that kind of looks like a mini Eiffel Tower. It's 63.5 meters tall and was built in 1891 for a World's Jubilee Exhibition. Visitors can climb up 299 stairs to two observation platforms or take the elevator if they're feeling lazy. There's even a gift shop and a small café inside.
