Petrin Hill lies in the center of Prague and is covered almost entirely with parks.  The summit can be reached by a twenty to thirty minute walk or by a ride along the funicular railway from Ujezd Street in Lesser Town [Malá Strana].
At the bottom of the hill are the ghostly bronze statues of the Memorial to the Victims of Communism by Czech sculptor Olbram Zoubek and architects Jan Kerel and Zdenek Hoelzel.  The statues appear to disintegrate the further up one goes.  One of the statues was damaged during two bomb blasts in 2003.
I’ve read that the park is beautifully landscaped, but it’s quite hard to tell in the evening because the area is very poorly lit.

At the summit is a 60-meter tall version of the Eiffel Tower.  For a small admission visitors can walk up the tower’s 299 steps to the viewing platform.


The observation deck gives a great view of the city.  The most prominent landmark in the photo below is Saint Vitus’s Cathedral [Katedrála svatého Víta], which is located within the Prague Castle complex [Pražský hrad].
