The Sassanid Palace at Sarvestan is a Sassanian era building in the Iranian province of Sarvestan, 90 km southeast from the city of Shiraz. The Palace was built in the 5th century AD, and was either a gubernatorial residence or a Zoroastrian fire temple. The Sarvestan Palace was built by the Sassanian king Bahramgur, and dominates an immense, empty plain. The name Palace is a bit misleading, because the monuments function is not really understood. It may in fact have been a hunting lodge or even a sanctuary. The problem is complicated by the fact that there appears to have been a small building, just north of the Palace.
