There are many challenges and discrepancies between experts and historians about the character buried in this building. Some consider it to be the tomb of Tughral Beyk of Seljuk, and it is stated in the “Mahmalottavarikh” book on page 465 that "Sultan Tughralibek died in the city of Rey and his tomb is there." Turkish historian, Faregh Sumer also considers the burial place of Toghrol in the same location. Other writers consider this place to be the burial place of Khalil Sultan, the son of Timur Lang and his wife Shadalmolk in the 15th century. In the book of Reye Baastaan (the ancient Ray) authoring Hassan Karimiyan is mentioned that a group attributes this monument to Fakhr Deilami. Mohammad Mohit Tabatabai considered this building to belong to Ibrahim Khawas and he himself was buried next to this tower in 1992.

As mentioned above, Toghrol Tower was first renovated in 1922 and at the end of the 35th year of the reign of Nasser al-Din Shah. This restoration was carried out by the order of the Shah and by the Chancellor Amin al-Sultan and by Abul Hassan Khan Memarbashi and marble slabs were installed on the entrance of the building. This reconstruction saved the building from the danger of destruction, but destroyed the elegance of the old works and the tomb of the Kufic inscription. After the Revolution of 1978, this building was abandoned until it was rebuilt again in the early seventies, and seriously began in mid-1998 and ended in the winter of 2000. Reconstruction is currently underway by District 20 of Tehran Municipality in an area of 2 hectares in order to expand and build a cultural center, library, museum and restaurant.
