Mariánské Lázně

Mariánské Lázně is a spa town in Cheb District in the Karlovy Vary Region of the Czech Republic. It has about 12,000 inhabitants. Most of the town's buildings come from its Golden Era in the second half of the 19th century, when many celebrities and top European rulers came to enjoy the curative carbon dioxide springs.

The town centre with the spa cultural landscape is well preserved and is protected by law as an urban monument reservation. In 2021, the town became part of the transnational UNESCO World Heritage Site under the name "Great Spa Towns of Europe" because of its springs and architectural testimony to the popularity of spa towns in Europe during the 18th through 20th centuries.
