The whole hill may be divided on several parts. The central part is formed by orchards in Nebozízek, separated from the Kinský Orchards by a Hunger Wall on the south and from the Seminar Garden by a funicular on the north. The mountain top, point above the rocky part of the Seminar Garden, precincts of the lookout tower, church of St Lawrence, upper funicular station, Štefánik’s observatory and former fortification lands are together called Petřín. The name has been most probably derived from the Latin word patrae, which means rocks.
In the remote past Petřín was covered with dense forests. Progressively, the place had been cultivated and vineyards and orchards rose there and finally Petřín was changed in public orchards, which hugely used for short-term recreation. Its sloping terrain was tissued with many paths, including the main one, which has been called the Observation Path.
The church of St Lawrence had been built there in Romanesque era and it was successively extended and reconstructed into the present baroque appearance. Later on other sacral buildings were constructed there. During the reign of Emperor Charles IV there was built the gothic Hunger Wall. The period, when vineyards were stretched on the Petřín slopes, is recalled by the building of Nebozízek. In the period of the so-called technical revolution Petřín Hill was given the lookout tower, the funicular and the observatory. You may best identify the above-mentioned constructions, illuminated in the evening hours, from the promenade on the Smetana’s Embankment.
