The Sächsische Schweiz (Saxon Switzerland) is a rural district (Landkreis) in the south of the Free State of Saxony, Germany. It borders the Czech Republic. Vehicles registered in the district have PIR, for the city of Pirna. This is because the districts own abbreviation would be SS, and this is not used because it is the same as the Nazi SS, the Schutzstaffel
The district was created in 1994 when the two districts Sebnitz and Pirna were merged.
The district is named after the landscape - the Saxon Switzerland - as it is the most mountainous region of Saxony.
