Zvuky Prahy / Sounds of Prague

The Petřínka spring flows out of a bronze tube from granite blocks and falls into an oval trough and down the drain. The inscription on the brass plaque reading "Petřín Spring 1982" commemorates the year when the spring was restored to its present form. In 1986 there was a ceremonial opening of the spring with the participation of Elmar Klos, who lived in a house on the top of the Hunger Wall. The spring was then adorned with a statue, stolen within two days. The source of the water was supposedly changed from in the past. Today, a small trickle comes out of the sandstone outcropping above the well and is led into the well. The water is potable and the tributary fluctuates, occasionally in regular periods the pipe becomes foamy as it reacts to the chnaging level in the well. The entire Petřín-Kinská, Nebozízek, Seminářská, Lobkovická and Strahovská gardens form an extensive water reservoir. The water from the Strahov and Petřín springs used to be distributed by pipeline to the palaces, hospitals, monasteries, fountains, wading pools, schools, etc., in Malá Strana. Today, almost all the springs drain into the sewage system and end up in the Vltava via Čertovka. Which is a pity.
