Al Thaqab Fort is a historical watchtower fortification situated in the Al Zubarah region of Qatar, near the Al Zubarah Archaeological Site, which is a UNESCO World Heritage Site. The fort is emblematic of the defensive structures that are scattered across the Qatari peninsula and particularly notable for its role in the monitoring of water wells and protection of the northwest coastal settlements. Built of traditional Qatari limestone and mud, Al Thaqab Fort features a prominent rectangular shape with three circular watchtowers and one rectangular tower. Historically, it served as an outpost to defend against invaders and to oversee the nearby pearling sites. Presently, the fort stands as a testimony to the area's rich history, drawing visitors interested in the heritage and old military architecture of Qatar. The archaeological and cultural significance of Al Thaqab Fort, along with its ties to the greater Al Zubarah fortification system, offers an insightful glimpse into 18th and early 19th-century Gulf defense strategies.
