Earlier this month (April 2022), it was reported that Ali Asadi, the head of the Fars Archaeological Board, has told reporters of the latest discovery in the Persepolis area. Asadi stated that the excavations were carried out with the aim of extending the waterways in the southern courtyard of Tachara Palace. The excavations have revealed an east-west waterway which diverts towards the south and extends all the way to the Palace of Ardashir Pāpakan. Herein were found hundreds of artifacts and adorned stones, which seem to be from the main stairs of the palace and were most probably intentionally broken.

Asadi also believes, due to the large number of stones discovered, that some of the complexities of the northern facade of Ardashir Pāpakan Palace, which is one of the most difficult archeological sites of Persepolis, will become more comprehensible.

Tachara Palace, or the Mirror Palace, was the winter palace of Darius the Great and was one of the first palaces to be discovered in the Persepolis area. It became known as the Mirror Place (The Hall of Mirrors) as the stones used to build the front of the palace are reflective.
