Khaydalu was a city in ancient Elam civilization. Some scholars believe that the city was located where today Khorramabad is.[1] In 640 BC, Ashurbanipal, the king of the Neo-Assyrian Empire, conquered Elam and destroyed Khaydalu. Afterwards, the city became a part of Assyria. In the Sasanian Empire the city named Shapur Khast was built upon where Khaydalu once was.[2]
