[1] Considered to be a masterpiece of Iranian architecture, according to Oleg Grabar, it achieves an "almost perfect balance between a purpose (princely glory beyond death), a form (cylindrical tower transformed into a star), and a single material (brick)".

[1] According to Sheila S. Blair (2002), the building's entrance contains some of the earliest evidence of the development of the moqarnas structure (i.e. stalactite vaulting) in Iran.

Taking its conical roof into account, the tower measures c. 50 metres (160 feet) above ground; this is three times its exterior diameter.

Sheila S. Blair notes:[1] The tomb is entirely constructed of fine-quality baked brick whose pale yellow color has been turned golden by the sun.

The technical quality of the construction is clear from its almost perfect survival despite the ravages of time, climate, and even reported shelling by the Russians.

[9] According to Melanie Michailidis (2009), Zoroastrian influence is "manifestly present" in the tower tombs of northern Iran, and can be seen in their height, purpose, and forms.
