Bad Salzuflen is a city in the Lippe district of North Rhine-Westphalia, Germany. It has an area of 100.07 km² and 55,020 inhabitants (2003).
Bad Salzuflen, known for its saltwater and thermal baths, is an old city with many historical buildings.
The word Bad is normally used as a prefix (Bad Vilbel) or a suffix (Marienbad, Wiesbaden) to denote that the town in question is a spa town. The word Kurort is also used, meaning a place for a cure. However not all Kurorte are spa towns; there are also Kurorte which are visited for their pure air (Luftkurorte, for example).
A spa town is a town frequented, in times past, for health reasons, to "take the waters". The name derives from the Belgian town Spa, and in continental Europe, a spa was known as a ville d'eau (town of water).
