Petřín is the wooded hill on the left bank, and the steel lattice tower on its summit gives one of the widest views in Prague. From the platform you see the castle strung along its ridge, the spires of the Old Town, the river bending through them, and on a clear day the hills of Bohemia beyond. The tower went up in 1891 at roughly a fifth of the Eiffel Tower's scale, and 299 steps spiral up it around a lift shaft.
The hill rises about 130 metres above the river, and the slope under the tower carries older things: orchards, rose gardens, a Baroque church and a funicular railway. Across it runs the Hunger Wall, a fortification Charles IV had built in the early 1360s. Members of the Czech Tourists' Club paid for the tower after visiting the Paris exposition of 1889 and coming home impressed. The hill below is a park the city treats as its own, and in spring the orchards flower and half of Prague lies on the grass.
