Ali Tusi Tomb
It is in the upper part of Sulu Sokak, known as the oldest street of Tokat, on which Danishmend and Seljuk works are located. It was built by Ebü'l-Kāsım-ı Tûsî, the vizier of I. Alaeddin Keykubad, in 631 (1234) while he was still alive. Although it is known as Ali Tusi Tomb among the people, it is clearly understood from the inscription that this name belongs to the father of the person lying in the tomb. The mausoleum has a square plan and its body has turned into an octagonal high dome drum from the semi-level. Although the dome with squinches covering the interior was covered with a pyramid-shaped cone from the outside, there is a roof covered with tiles in the place of this destroyed cone today. The walls are made of brick and covered with a thick dirty yellow plaster. There are two windows on the front that make up the most striking part of the tomb. The window openings are located in the lower half of a rectangular niche, which starts from the ground level and is more than twice as high, and above them there is a high pediment with pointed arches. Two verses are inscribed with turquoise tile mosaic on a dirty yellow background between the upper sills of the three-level inward niches and the pediment arches. The other parts of the niches and the inside of the pediments are decorated with geometric patterns made of intersecting hexagons made of turquoise, dark blue and purple tile mosaics. Above the window niches, there is an elongated, two-line inscription protected by a narrow eaves. In the southeast corner of the tomb, a fountain without an inscription with an arch and a concave niche was built by carving the wall in late periods.
