Bahla Fort
Bahla, Oman
Bahla Fort (Qalʿat Bahlāʿ) is one of four historic fortresses situated at the foot of the Jebel Akhdar highlands in Oman and was the country's first UNESCO-listed fort added in 1987. In 1988, the Archaeological Sites of Bat, Al-Khutm and Al-Ayn became the second Omani site to be declared World Heritage by UNESCO. Bahla Fort underwent massive restoration efforts and reopened in 2012. However, the complex lacks in visitor information. There are no exhibits or brochures available to learn more about this large space or guides at hand to provide further details, so people either need to go on a tour or explore on their own.
