Dumat ul Jandal is another interesting place in the province Al Jawf, almost 37 km away from that has a beautiful Mard building just like a castle which is called as Fort giant. The name Dumat ul Jundal is derived from the phrase “Dumah of Stone” because it was the place occupied by the renowned people in the ancient times. However the fort is built at the height of 2000ft on the territory of Saudi Arabia. Though this place is dry looking with mud and brick made walls and buildings, it has a great history for the interested archaeologists who can search for different secrets embedded in its dwellings. The architectural aspects attract many tourists from different parts of the world toward Saudi Arabia.
