Complex Some of the structures of the Laleli Mosque's kulliye have disappeared over the years, but the mausoleum facing Ordu Street remains. It is an octagonal domed türbe and contains the graves of Mustafa III, his son and successor Selim III, and his daughters Hibetullah and Fatma Sultan and Mihrimah Sultan. The interior is decorated with reused İznik tiles from the 16th century, and a band of calligraphy encircles the upper walls. In the graveyard next to the türbe is the tomb of Adilşah Kadın, set within an ornate bronze grille representative of Ottoman metalwork at the time. The waqf (endowment) of the complex also included a number of buildings throughout the city which provided revenues for the upkeep of the mosque and its külliye. Among the notable inclusions were two caravanserais: the nearby Taş Han (formerly known as the Çukurçeşme Han) and the larger Büyük Yeni Han located in the commercial district north of the Grand Bazaar. The Tayyare Apartments were built in 1922 next to the mosque on the ground of 1911 burnt down Koska Madrasa, which belonged to the mosque's complex. The buildings were redeveloped into a five-star hotel.
