Jebel Akhdar highland in Oman is home to four historic fortresses, one of which is the Bahla Fort. The Bahla Fort became the first, and only UNESCO listed Fort for Oman and it was added in 1987. After going through massive restoration processes, (from 1988-2004 and even further) the Fort reopened as a tourist attraction in 2012. Another interesting fact is that there is not much information about this place. So, if you are here, you have to explore it all on your own.
The Bahla Fort is said to have been built by the Banu Nebhan tribe between the 12th and 15th century. The Banu Nebhan tribe was eminent for controlling the trade of frankincense at that time. A citadel oasis and an ancient wall (which spanned 13km) could also be found standing adjacent to the Fort (although most of the wall is left in ruins). Though the majority of the oasis is destroyed, yet some houses still stand. The weak structure of the Fort (built with bricks of mud and straw) was mostly responsible for its destruction through erosion. Multiple erosions and landslides forced UNESCO to put this Fort in the list of endangered ones until complete rehabilitation in 2004. There are three main sections inside the Bahla Fort, Al-Qasabah (oldest part), Bait al-Hadith (or new house built by the Ya’riba dynasty 1624-1743) and Bait Al-Jabal (which was erected in the 18th century).
