NeptunbadThe Neptunbad was built in the art-nouveaux-style in 1912 by the Königlich-Preußischen Baurat Kleefisch as publish swimming bath at ca. 5000 qm for sauna, swimming and relaxation. It got the state as a memorial in 1986, but had to be closed in 1994 cause of missing resources for a renovation. Finally it was sold to the Claudius Therme GmbH & Co. KG, which after a complete restauration reopened it in 2002 as Health Club & Spa. The old 13-meter-high and with gold covered bathing hall was modified to a fitness-room, the sauna offers also Japanese bathing.
