İsmet Efendi Sufi Lodge

The lodge was established through the endowment of a mansion purchased by its founder and dedicated as a dervish lodge.
The mansion structure endowed as the lodge suffered a fire; the existing wooden harem and selamlık sections were rebuilt afterward.
The masonry tevhidhane of the lodge remained abandoned for a long time after the closure of the dervish lodges; in 1958, it was converted into a mosque with the addition of a minaret and a last prayer portico.
The northern section of the stone walls surrounding the wide garden of the lodge, including the main gate, was demolished in 1992 as part of a road-widening project; a concrete wall was built in its place.
During the same intervention, the cistern set into the wall, vaulted and domed on the inside and roofed on the outside, also disappeared.

It is also known by the name Mustafa İsmet Efendi Lodge.
The lodge has been regarded as one of the early and prominent centers of the Naqshi-Khalidi tradition in Istanbul.
Its founder, Sheikh Mustafa İsmet Efendi of Ioannina, died on 15 January 1873; a cemetery section associated with his deputies and postnişins took shape around the lodge.
The masonry section used as the tevhidhane has a two-space scheme covered with vaults and domes; during its conversion into a mosque, a minaret and a last prayer portico were added.
