Falak-ol-Aflak

Falak-ol-Aflak, also known as Shapur Khast Castle, is a historic fortress located atop a prominent hill in Khorramabad, the capital of Lorestan province in Iran. Constructed during the Sasanian era between 224 and 651 CE, the structure exemplifies classic Sasanian architecture. The castle sits strategically where the Khorramabad River flows past its eastern and southwestern sides, providing natural defensive barriers. Originally surrounded by a two-layered rampart with twelve towers, only two of these original towers remain today. The foundation measures approximately 300 by 400 meters, and the entire complex rises about 40 meters above the surrounding landscape. Its elevated position was intentionally chosen to allow wind to circulate through the stone and wood materials, serving as a natural dehumidifier to protect the foundations from moisture damage.

Throughout its long history, the site has served various functions, most notably operating as a prison until 1968 during the Pahlavi era. Following this period, it was converted into a museum complex and is currently managed by the Iran Cultural Heritage Organisation as a protected historical site. The castle stands as a significant cultural landmark, offering insights into ancient Iranian military engineering and regional history. However, the structure recently faced modern threats; reports indicate that during the 2026 Iran war, the castle sustained structural damage resulting from United States and Israeli military strikes. Despite this recent conflict-related damage, Falak-ol-Aflak remains a monumental symbol of the region's heritage, continuing to draw attention for its architectural grandeur and resilience through centuries of changing political landscapes.
