Straddling the road between the corniche and the old walled city, this museum, with the original gates used until the 1970s to keep land-bound marauders out, marks the position of the old city wall and introduces Muscat proper. Though the museum's exhibits are of limited interest, the site provides an excellent vantage point for the corniche and the diwan.
A drive up to the aerial mast on the neighbouring hill gives an even better view of Mutrah and Muscat before dropping down to Al Riyam Park in Mutrah.
