The Lakh Mazar inscription is a pre-historic stone wall estimated to be more than 7,000 years old and located near the Kooch village, about 29 km away from Birjand, Iran.
It is the most valuable memorial plaque in eastern Iran due to its diversity and historical importance.
Each inscription has a unique style from the period of its creation and can be analyzed independently of the others.
There are four pictorial lines, 81 inscriptions dated to the Pahlavi, Parthian, or Sassanid empires, 42 with Perso-Arabic script, and 67 rock paintings which have yet to be identified.
The Lakh Mazar inscriptions contain swastikas or spinning wheels inscribed on stone walls.
