The word 'masmak' means strong, thick and fortified which is a perfect description of this fort. The castle was constructed during Mohammed bin Abdullah bin Rasheed's reign and came under King Abdulaziz's rule, when Riyadh was conquered. This represents the turning point in King Abdulaziz’s efforts to unify the country. Today, it's open to the public, as the Al Riyadh Development Authority has converted it into a museum. It is a very interesting place to visit as one quickly observes the ways of previous generations.
