Petřín Lookout Tower (Petřínská rozhledna), Prague

Opposite the castle above the Vltava River stands Petrin Hill which features a replica of Paris's Eiffel Tower. Built in 1891 in honor of the Land Jubilee Exhibition, the tower is 63 meters high with 299 steps. It is open to the public and offers a panoramic view of Prague. Surrounding the tower are gardens and several small churches including a wooden one, the logs for which were brought in from the Ukraine in 1929. There is also the Mirror Maze, a series of convex and concave mirrors built for the exhibition of 1891. To get to the tower from Prague itself, there is a funicular railway running every 15 minutes from near Ujezd, just across the river from the National Theatre (metro tickets are valid on this railway).
