“Two climbers came across this inscription while climbing on their way near Tangeh Bolaghi in the Pasargadae region,” a local official in charge of the protection of cultural heritage said on Wednesday.
They immediately informed officials of the Pasargadae, Persepolis World Heritage Site reported.
The World Heritage Site stated that the inscription dates back about 1,500 years.
Experts say the inscription is a dedicatory letter that informs about the construction of a bridge, dam, and road, and a blessing has been prayed for its builders.
Inscribed on a rock piece measuring 90 by 40 cm, the inscription is written in the Pahlavi language.
