Nakhal Fort pictured above is just one of many beautiful, grand old fortresses standing watch over our mystery country. It is located in the north of the country, in the foothills of the Western Hajar Mountains, about 75 miles west of the national capital Muscat.
The fort has been expanded and renovated many times over the centuries but its origin is pre-Islamic, so sometime before the 7th century. The fort wraps around the top of a natural prominence, giving it a unique shape that can appear both an imposing monument and an extension of the rugged landscape.
Can you name that county?
