Toghrol Tower (Persian: برج طغرل‌) also transliterated Toghrul, Tughrol, or Tughrul) is a 12th-century monument, located in the city of Rey, Tehran province, Iran. Tuğrul Tower is near Rashkan Castle.

The 20-metre-tall (66 ft) brick tower is the tomb of Seljuk ruler Tughril, who died in Rey in 1063. Originally, like other monuments of its time, it was capped by a conical dome (گنبد, gonbad), which collapsed during an earthquake.^[when?]

The thickness of the walls varies from 1.75 to 2.75 meters. The inner and outer diameters are 11 and 16 meters, respectively. The exterior shape is that of a polygon with 24 angles in its design, which is thought to contribute to the structure's stability against tremors.

At the top of the tower, Kufic inscriptions were originally observable.

The tower is protected by Iran's Cultural Heritage Organization.

In some texts this place is called Burj Khalifa Yazid. According to some experts' ideas, this tower is like a clock pointer and the time can be recognized by the sunshine on its congresses.
