Alāeddin tower or Alā'douleh tower
The Alāeddin tower or Alā'douleh tower is an ancient building from the period of the Seljukids in the Seljuk style dating from the late seventh century of the lunar Hegira which is located in the center of the city of Varāmin, north of the Jām'e mosque and in the wing southeast of the main square of this city. This building resembles regal tombs and is the burial place of Hassan Alā'douleh, governor of that time of Rey.
Inside the building there was a cylinder without decorations and the interior walls, after having been worked in brick, were whitewashed. For the exterior decorations of this tower which include: a multilateral cylinder - 32 stellar sections - and a cylindrical dome with two covers, the turquoise tiles and sun-shaped bricks were used.
In the room below the tower there is a crypt with the design of an Iranian cross located lower than the ground level. The building of the Alāeddin tower has an epigraph from which it is clear that the construction of the tower dates back to the year 1298.
This building with two entrances, a height of 12 meters (main part) and 54 meters (the dome), is one of the earliest examples of Iranian mausoleum towers that over the course of hundreds of years has undergone erosion and last years has been restored and is currently considered a tourist attraction and temporary place for various exhibitions
