Closed until May. Just left of Centennial Hall's main entrance you'll find the 'Pergola' - a colossal, semi-circular, ivy-covered colonnade winding around one of the city's most magnificent and popular attractions - the multimedia fountain. Unveiled on June 4, 2009, in honour of the 20th anniversary of the first free elections in post-war Poland, Wrocław's fountain projects water up to 40 metres high through an array of 300 different nozzles which have the ability to rotate, gyrate, pulse and even create a 700 square metre screen of water on which animated projections can be displayed; all the while music orchestrates the show through the park's speakers.Equipped with 800 lights of varying size and strength, the Wrocław Fountain even has pyrotechnic capabilities with fireworks and lasers implausibly shooting out of the large semicircle basin next to Centennial Hall. The result is one of the most dazzling, delightful displays of light, sound and water you'll ever see; in fact only a few such fountains exist in the world (although those show-stealing jerks in Warsaw recently got themselves one). Certainly nothing puts a stamp on the end of communism like indulging in some outrageously expensive gadgetry; the cost of running this show on a regular basis must be enormous, but you can see it for free from May until the end of September. The fountain comes to life hourly starting from 10:00 (the timing of the last show changes each month), and performances vary from 3.5 to 18 minutes with a short or long programme of classical music (Wagner, Beethoven), 'modern' music (Apocalyptica, Faith No More), or 'pop' music (Daft Punk, Madonna). The real stunners, however, happen just after dark on Fri, Sat and Sun, when the full functionality of the fountain is on display, including lights. Having drawn crowds of up to 20,000, this surely something you shouldn't miss. View the daily schedule in detail (and in English!) online.
