Haliliye Madrasah is in the town of Gümüş in Gümüşhacıköy. It was commissioned by Halil Paşa, the governor-general of Sultan Çelebi Mehmet. Halil Paşa, formerly the bailee of the silver mines in the area, was later promoted to governor-general in 1413. He had the madrasah built in 1415. The building has a rectangular plan. The bearing walls built of broken stones have been supported with fillings in the repair works carried out recently. The courtyard, which was originally roofed with a dome, was fringed with the present wooden portico after the dome collapsed. The epigraph is placed above the door on the southern wall which is the main entrance to the madrasah. Once inside, the rectangular courtyard, fringed with a portico with a flat roof supported by wooden piers and lancet arches, welcomes the visitors. The classrooms and chambers are aligned beyond the cloisters created by the wooden piers. The vaulted chambers towards the middle are larger and each has an epigraph of its own over its entrance. Each chamber has a small window looking outside. The tiled roof covering the portico and the chambers are later additions to the building.
