The structure was registered as a national monument of Iran in 1997.
Unlike most of the caravanserais that have rectangular plans, Tajabad is circular.
A total of 26 rooms are located in front of an inn, the floor of which is paved with stones. The building hosts two water wells.
The main materials used in the construction of Tajabad Caravanserai are red brick and mortar (Sarooj).
