Bahla Fort is an ancient fortification located in the town of Bahla in Oman, around 190 km from Muscat. It is believed to be one of the oldest and largest forts in Oman, and is listed as a UNESCO World Heritage Site.

The fort dates back to the pre-Islamic period, and the first fortifications were built in the 12th century by the Banu Nebhan tribe. The fort was expanded in the 13th and 14th centuries, and was a major center for pottery production and trade. The fort played an important role in the region's history, serving as a stronghold for local rulers during times of conflict.

Bahla Fort is known for its impressive walls, which are made of adobe and extend for several kilometers. The walls are up to 15 meters high in some places, and are fortified with towers and gates. The fort also contains several inner courtyards, buildings, and underground chambers.

Today, Bahla Fort is a popular tourist attraction and is open to visitors. The fort has been partially restored, and visitors can explore the impressive walls, towers, and courtyards, as well as the small museum inside the fort. The town of Bahla itself is also worth a visit, with its traditional architecture and historic souq.
