## Spa

The first mention of springs is from 1454. The spa was founded by the Metternich family, which owned the town's castle.
In 1822, Count Richard Metternich built a spa and six springs around the area. The area shortly became more popular after the spa was built. In 1872, a railway was built, which helped the growth of the spa and the town.
After 1950, during the whooping cough epidemic, children were treated in the spa. Since then, only children were treated in the spa. In 2013, treatment was again extended to adult patients.
