A Study of the Architectural Remains of the Sasanian Site of Tol-e Qaleh Seyfabad -Kazerun: A Suggestion about the Function

The archaeological site of Tol-e Qaleh Seyfabad, with an area of approximately 160 hectares, is one of the important sites of the Sasanian period, which was formed about 500m west of Parishan Lake, in the southwest of Kazerun city, on the natural hill so-called Tol-e Pahan. Due to the building of the Kazerun-Shiraz gas pipeline between 1984 and 1986, the middle part of this site was severely destroyed. Archaeological excavation, as well as ground surveys, show that the exposed building/fort in Tol-e Qaleh Seyfabad has a quadrangular structure, each side of which is probably between 75 and 80 m long, and there were probably four towers in its four corners. The low thickness of the external wall, the type, and quality of construction materials used in it, as well as the dimensions of the interior spaces/units, may indicate that the building was not very high. The spaces adjacent to the northwestern principal wall are generally small and are used for storing and processing agricultural products.In the four corners of the Nakhlak fort located in the intermediate region of Naein and Anarak, the towers are similar to Tol-e Qaleh Seyfabad’s tower, although it has a different plan. In addition, other defensive buildings such as Fulayj fort in Oman, Gorgan Wall fortifications, and Abu Sharifa fort in Mesopotamia are among the defensive structures that are similar to the Tol-e Qaleh Seyfabad building in terms of plans and towers.
