Sofia area was famous for its mineral springs so it’s no surprise they had public baths since 16th century.
Sofia public Mineral Baths (Sofiyska gradska mineralna banya ) was built in 1908 on the same spot where the former Turkish baths were. Although the main style is Vienna Secession the architects used a lot of byzantine religious elements for decoration, the three domes and the art nouveau tiles gives makes it looks nice.
The baths opened to the public in 1913 and operated non stop (although it was bombed during WWII) until 1986 when they realized that the roof was ready to collapse.
It was closed to visitors when we went there (it seemed under renovation) so I couldnt check the interior. From what I know it will turn into a museum. By the way we noticed many locals with filling bottles with mineral water from the taps next to the building.
Due to the warm springs rising in Sofia, both the Romans and Ottomans built public baths. The current baths were built in 1913 to a Byzantine church design. With its three egg-shaped domes and Art Nouveau tiles, the building is a colourful sight. The baths are currently undergoing renovation and are closed to the public.
The Central Baths (Tsentralna Banya) were completed in 1908 on a site of a former Ottoman bath. The building includes different archtitectural elements from Viennese Secession to Art Nouveau.
In 1986 it was closed as a public bath, due to its urgent need for restoration. The plan is to reopen the building in the near future as Sofia's first city museum.
The Central Baths can be found in a small park just behind the Banya Bashi Mosque, which is located opposite of the Central Market Hall (Tsentralni Hali).
From the earliest times, Sofia's main attraction's been its thermal springs, which are still in public use today, as a water source. What's more, you can see a mineral spring on the city's coat-of-arms.
The colourful building in the main picture was built on the site of a former smaller Ottoman bath. When it was opened in 1911, it had separate facilities for men and women. The hot mineral spring's been used for bathing and healing purposes ever since.
The present building was designed by the Bulgarian architect Petko Momchilov in 1906. Today, it's being restored. The inside will be a Museum of Sofia and a Thermal Healing Centre.
On the square in front of the baths, it's possible to taste the steaming mineral water (46°C/115°F) from public taps. In fact, a lot of people come to fill their bottles or containers with this water, rich in minerals.
Not exactrly a must see activity but I kind of like the building. It has mosaics on the facades.
It is built on the site of a former smaller Ottoman bath. Open for public in 1911 as a public bath it has separate facilities for men and women.
It is currently being refurbished to become partly a museum of the city and partly a hydrotherapy center.
Its front yard is usually full of people queuing to fill hot water from the mineral spring.
