The Sasanian, the last Iranian dynasty before the Arab invasion of Iran, overthrew the Parthians and ruled the region for more than four centuries between 224-651 AD. One of the structural characteristics of the Sasanian state was the establishment of an official religion and the concentration of political and religious sovereignty. The official recognition of the Zoroastrian religion led the Sasanian kings and priests to build numerous fire temples in various parts of Iran, and many archaeological evidences of Sasanian era burials have been found, which are intertwined with art. The kings enriched the art of this period by creating rock carvings to display various matters. A rock carving in the Sasanian style was accidentally discovered a few years ago at a local airport in England. When this discovery was reported in the early days of 2023, the main question was whether it was an independent rock carving that had been detached from the mountain or whether it belonged to a structure? Based on the library studies and comparisons made with other works in this article, it seems that the newly discovered Sasanian rock carving from Stansted Airport in London was likely part of a stone structure similar to a fire altar or a Astōdān (one type of Ossuary), and it most probably dates back to the early Sasanian period.
