In the 1770s, the structure was converted into a Sadiyya lodge.
It suffered heavy damage in the fire of 1829; afterward, it was repaired and continued to function until 1925.
In 1909 (Hijri 1327), it was revived by Sheikh Âşir Efendi and Ayşe Sıdıka Hanım; the inscription recording this intervention is associated with the main gate.
After its destruction in the 1940s, it remained in ruins for a long time; in 1948, the building was partially repaired and converted into a dwelling.
The revival and restoration process that began in 2007 was completed in 2012.
Today, the building is used for cultural and artistic activities.
Prominent Features:
The names Sa‘diler (Sadis) Lodge, İsfendiyar Lodge Masjid, and Yağcızade Lodge Masjid were also used.
The name “Sa‘diler Lodge” became established because the rites of the Sadiyya order were performed inside the masjid.
In the small cemetery section, the founder’s grave and a gravestone dated 1637 (Hijri 1047) are preserved.
The poetic inscription associated with the main gate and recording the 1909 revival is a readable document of the building’s history.
The complex was described through the composition of the tevhidhane and the three-storey wooden meşruta; it has survived to the present not as an intact whole, but through limited remains and the process of revival.
