Petà ÂÃÂn () is a hill in the centre of Prague, Czech Republic. It rises 327 m above sea level and some 130 m above the left bank of the Vltava River. The hill, almost entirely covered with parks, is a favorite recreational area for the inhabitants of Prague. The hill (in German known as Laurenziberg) is featured prominently in Franz Kafka's early short story "Description of a Struggle" and briefly in Milan Kundera's novel The Unbearable Lightness of Being.
The chronicler Cosmas describes Petà ÂÃÂn as a very rocky place, the hill is allegedly called Petà ÂÃÂn because of the large number of rocks (Latin: petra). Since ancient times, stones were dug and were used to construct buildings in Prague. Medieval defence wall, the Hunger Wall was built on Petà ÂÃÂn Hill during 1360 - 1362, by the order of king of Bohemia Charles IV. The Petà ÂÃÂn Lookout Tower, which strongly resembles the Eiffel Tower, was built atop a hill in 1891. Other sights include the Rose Garden, Mirror Maze, Cathedral of Saint Lawrence, and St Michael Church.
The summit of the hill is linked to Prague's Malá Strana district by the Petà ÂÃÂn funicular, a funicular railway that first operated in 1891.
