At the end of XVIII - early XIX centuries, this small, lively and charming spa town has attracted celebrities such as Strauss, Wagner, Kafka, Fraulein, Twain and Edward VII. Tastefully decorated spas and hotels cling to the slopes in lush mountain forests. The city and surrounding hills dot the hundreds of mineral springs with a high content of carbon dioxide and iron. Many of them are marked with neat colonnades and stately pavilions. The most famous Cross Spring, surrounded by a colonnade with a dome.
