The Central Bathhouse has been designed by the Bulgarian arhitect Petko Momchilov in 1906. The hot mineral spring on the spot has been used for bathing and healing purposes. It has not been functional for some time. Now is being restored, to look on the outside same as it did, when it was built. The inside, for the most part, will be a Museum of Sofia History. A fraction of the building will be used as a Thermal Healing Center.
The mineral water has been piped out to nearby place, from where people can fill their empty bottles and other containers and take mineral water home for free.
