Ümmü Sultan Şah Mausoleum

Also known as the Hatuniye Mausoleum, it is the tomb where Sultan Shah Hatun (Handaze Hatun), the sister of Aydınoğlu Mehmet Bey, is buried. It is the oldest known structure of the Aydınoğulları Principality. The two-line construction inscription found on the flattened entrance arch of the building states that it was completed in the early days of May 1310. The mausoleum is located in the center of the city, in the middle of a complex structure along with the Aydınoğlu Mosque and a madrasa, which no longer exists today.

The mausoleum was generally repaired by Nedim Onat in 1964. A mixture of rubble stone and brick was used on all its facades. The ground of the entrance section in the southwest direction was elevated with marble, and the door opens outwards with a pointed arch. Inside the mausoleum, there is a single stone sarcophagus made in a rough style.

The hexagonal plan of the mausoleum has no equivalents in Seljuk architecture. This plan distinguishes the architecture of the Principalities period from the Seljuks. Moreover, the features that separate the structure from Seljuk architecture include its domed upper covering and the plainly kept entrance side. (Anonymous)
