The Banya Bashi Mosque is a historic indoor mosque located in central Sofia on Knyaginya Maria Luiza Boulevard, close to the Central Mineral Baths and the city’s so-called “Square of Tolerance,” where several major religious buildings stand near one another. Built in 1566–1567 by the famous Ottoman architect Mimar Sinan, it is the only functioning mosque in Sofia and one of the city’s oldest preserved buildings. Its name means “many baths,” referencing the natural mineral springs beneath the site, which are still active today. The mosque is easily recognizable by its large central dome and slender minaret.

There is no entrance fee, but visitors should be aware that Banya Bashi Mosque is primarily a working place of worship, not a tourist attraction. Sightseeing is usually possible outside of the five daily prayer times, generally from morning until early evening (roughly around 9:00–18:00), though exact access depends on prayer schedules, Friday midday prayers, and Islamic religious holidays, when the mosque may be closed to non-worshippers. Visitors must remove their shoes before entering, dress modestly, and women are typically asked to cover their heads with a scarf. Quiet, respectful behaviour is expected at all times.

Inside, the mosque features a calm and elegant prayer hall decorated with Islamic calligraphy, geometric patterns, and colourful tilework, all beneath a wide, airy dome. It can become especially busy during Friday prayers, when worshippers gather from across the city. The mosque can be visited year-round, and because it is centrally located, it fits easily into a walking tour of Sofia’s historic core. For the best experience, visitors should plan their visit between prayer times and allow around 15–20 minutes for a respectful look inside.
