The Jouf region is distinguished by its castles and forts that reflect various historical periods.

Zaabal Castle is on top of a mountain to the north of Sakaka city in a distinctive location, rising out of the rocks as if it were a natural extension of them.

It dates back to the Nabatean era extending from the 1st century B.C. to the 1st century A.D. The current building dates back about 200 years and is surrounded by a wall of stone and mud. It has four conical towers that are several meters high and there are two rooms inside the castle.

The castle was one of the strongest forts of its time and was used to protect the people of Sakaka during wars and aggressions. It is used to secure the commercial road that passes through the region and links Iraq and Syria.

In the castle yard, there is a carved basin to preserve water. The area surrounding the castle is being developed through restoration and building works compatible with the urban and archeological identity of the castle to increase its appeal to tourists and visitors as it is considered an important historical and touristic landmark.
