Located in Birgi, the Sultan Şah Mausoleum, also known as the Hatuniye Mausoleum, dates back to the period of the Aydinid Principality. According to the inscription above the surviving entrance gate, this mausoleum was built in the 14th century in honor of Aydın Kızı Hatuniye (Sultan Şah Hatun), who is believed to be the daughter of Aydın Bey and the sister of Aydınoğlu Mehmet Bey. For this reason, it is commonly referred to as both “Sultan Şah Mausoleum” and “Hatuniye Mausoleum.”
With its proximity to the Great Mosque, the mausoleum stands out as an integral part of the region’s architectural fabric. The hexagonal body of the Sultan Şah Mausoleum is an early example of a rare architectural form that began to appear in Anatolia in the 14th century. Its domed roof reflects the architectural traditions of the period.
Mausoleums are considered special spaces where the material and spiritual realm intersect. Situated in the historical center of Birgi, which was shaped around the Great Mosque during the Aydinid Principality period, the Sultan Şah Mausoleum symbolizes the community’s deep connection to spiritual values. Its simple architecture and modest presence serve as a reminder of the transience of worldly life.
