Pirna is located near the Sandstone Mountains in the Elbe valley , where the nearby rivers Wesenitz , in the north , and Gottleuba to the south , flow into the Elbe . Pirna is also called the " gate to the Saxon Switzerland " ( Ger : '' Tor zur Sächsischen Schweiz '' ) . The Saxon wine region ( '' Sächsische Weinstraße '' ) , stretches from Pirna over Pillnitz , Dresden , and Meissen to Diesbar-Seußlitz , was dedicated in 1992 . In August 2002 , the town suffered great damage in the widespread flooding in Europe at the time . This was particularly unfortunate as it undid many well-executed restoration schemes carried out post 1990 re-unification
