Banya Bashi Mosque – A Symbol of Tolerance in Sightseeing Sofia
Banya Bashi Mosque is the only working mosque in Sofia today. It plays an important role in sightseeing Sofia. The mosque is also called Molla Efendi Mosque or Kadi Seyfullah Mosque. Long ago, Sofia had around 70 mosques. Now, only Banya Bashi remains.
The mosque was built by Kadi Seyfullah Efendi in memory of his late wife. It stands as a peaceful symbol of faith and culture. You can visit this site during one of our private Sofia tours.
Sofia – A Crossroad of Cultures
Sofia was once a major Ottoman center in Europe. It later became a key trade and government city. This led to the arrival of many travelers and merchants. Sofia grew quickly into a diverse and busy city.
There were once more than 100 mosques, libraries, bathhouses, and markets. Many religious buildings were lost after Bulgaria’s liberation in 1878. However, Banya Bashi Mosque survived. It now stands between a synagogue and a church. This makes it a strong symbol of religious harmony and coexistence in Sofia sightseeing.
Banya Bashi Square – The Historic Center
Before liberation, the heart of Sofia was Banya Bashi Square. All main streets led there. The area had markets, fountains, and the famous Mineral Baths. Free mineral water was even given to locals from a pavilion.
The square was also the resting place of two important donors: Emin Dede and Molla Seyfullah Efendi. Sofia sightseeing tours often include this historic square.

Thermal Springs and Architecture
The mosque was built over natural thermal springs. In Turkish, “Banya Bashi” means “many baths.” The hot water below is believed to have healing powers.
The mosque was designed by Mimar Sinan, one of the greatest Ottoman architects. It was completed in 1566, when Sinan was over 80 years old. That shows Sofia’s importance at the time.
The mosque has four domes and one minaret. Its structure includes a beautiful stone arcade with three domes covered in lead. Inside, the main prayer room is cube-shaped with a large dome on top. The dome symbolizes the sky, helping visitors feel peace and connection with God.
A Peaceful Place for Prayer and Reflection
Inside the mosque, floral designs cover the walls. Quran verses are written in calligraphy, creating a feeling of endless space. Visitors should remove their shoes. Women are asked to cover their heads and shoulders.
The mosque can hold up to 700 worshippers. On Fridays, speakers broadcast the prayers for those outside. The building may also have mysterious underground tunnels, adding to its charm.
