The Neustadt Kunsthofpassage is an artistic neighborhood in Dresden, Germany. Designed by artists Annette Paul, Christoph Roßner and André Tempel, this wall all covered with funnels and gutters is one of the strangest and unusual attractions in Dresden ' s student district in the new town. Kai lietus patenka į Vokietiją, ši nutekėjimo sistema virsta gražiu muzikos instrumentu. Tai vadinama "piltuvo siena". Gražus būdas švęsti gamtą.
