The Subası Mosque is located on the western side of the Eşrefoğlu Mosque in Beyşehir. In historical documents, the mosque is usually referred to as Demirli Mosque, although the term Subası Mosque is used occasionally.
According to its inscription, the building, which was constructed by Subaşı Şerafettin Emir Ahmet Bey in 1314—who was the Governor of Beyşehir during the time of Eşrefoğlu Bey Mübarizüddin Mehmed Bey—has served for centuries since then.
Although the inscription on the door of the mosque states that it is a madrasa, it is understood that the building functioned as both a mosque and a madrasa. Scholars believe that the primary purpose of the building, whose mihrab was added later, was as a madrasa, but it was eventually used as a mosque.
The mosque, which was closed to worship in 1933, fell into ruin over time. Its exquisite tiles were looted, with some smuggled abroad. A tile inscription from the mosque is now displayed at the Turkish Construction and Art Works Museum in Şehzadebaşı, Fatih district, Istanbul. Recently renovated, Subaşı Mosque offers a mystical and peaceful atmosphere to its regulars and visitors with its stone walls, entrance gate, and inscription.
