Detailed research and analysis tell us Qatar's towers were built to protect valleys where precious rainwater was collected and to watch for approaching ships. They would also have acted as observatories to determine the dates of the lunar calendar.
The Barzan Towers were built by Sheikh Mohammed bin Jassim Al Thani, founder of Umm Salal Mohammed village. Barzan is the name given to the western tower. At 14 meters high, it consists of three levels and, with its distinctive T-shape, is considered unique to the Gulf region.
The eastern tower, Al Burj Al Sharqi, also built with stones and cladded mud, has a more typical rectangular shape. Most of the early settlements had one or more towers that were cylindrical or rectangular in shape, usually built from stone.
