Seyyid Muhyiddin b. Seyyid Muhyiddin b. Seyyid Mahmûd and took its present form. Built in the 13th century as a foundation work, Seyyid Mahmud Hayrani Tomb has an interesting plan. At the bottom there is a square section made of rubble stone and brick. Above this, there is a second section, which consists of a hexagonal pulley with a hexagonal cone and is built of brick. The tomb, which has three cists on the lower floor, is especially remarkable with its tile decorations on the second section, which have been  destroyed on a large scale.
