Tarout Castle, also known as Tarout Fort, is a historic fortress located on Tarout Island in the eastern province of Saudi Arabia, near the city of Dammam. It is believed to have been built during the Ottoman era over older fortifications that date back to the Dilmun civilization. The castle's history suggests that it has been a central point of trade and settlement for various cultures over several millennia, owing to Tarout Island's strategic position in the Arabian Gulf.

Its design includes multiple rooms, gates, and towers that once served as lookouts and defensive positions. Over the years, Tarout Castle has faced challenges due to neglect and the elements, but conservation efforts have been made to preserve this piece of Arabian heritage. Visiting Tarout Castle provides a glimpse into the region's history, culture, and ancient architecture. The castle is a symbol of the island’s rich past and serves as a focal point for local folklore and stories of the past inhabitants.
