Built by Mehmed, son of Mahmud, son of Yunus, for his late son Ali, the octagonal tomb rests on the square plinth level and is covered with an octagonal pyramid spire. There are three sarcophagi placed in the tomb for Mehmed Beg, his wife, and his son Ali. According to the two-line thuluth Arabic marble inscription above its door, it reads: (the founder of the Mevlevi lodge, “Teke Beg” or) Mübârizüddin Mehmed Beg, son of Mahmud, son of Yunus, ordered the construction of a buk’a-i sharif (“holy place”) in the month of Shaban, Hijri 779 (December 1377), after the untimely death of his son Ali. According to the waqfiyya (Foundation Charter) of Sultan Korkut, in addition to Mehmed Beg’s son Ali, this tomb also contains the graves of Rumi’s descendants Kutbül’ârifîn Sheikh Mustafa Efendi and Kutbül’âşıkîn Eşşeyh Zencirşiken Mehmed Efendi.

There is a single vertical rectangular window on each of the seven façades of the octagonal building. The main door of the tomb is on the southwest façade. Topped with a depressed arch, the door is framed with a plain molding on the outside and a molded border on the inside. There are three rosette motifs right underneath the construction inscription. A handle and a ring-like piece carved from solid stone in the center of the façade above the door are considered a symbolic expression of the nickname Zincirkıran (“Chainbreaker”). There are monolithic stone decorations with floral and geometric patterns above the windows on the remaining seven façades.

The plastered interior of the tomb has an octagonal plan underneath a dome. On the marble inscriptions above the south, west, and northwest windows are one-line verses written in Arabic thuluth from the Al Imran Sura in the Quran (3/18 and 169). A wooden cist was placed on each of the three graves; none bear any inscriptions or decorations.
