Bait Muzna Gallery shows contemporary work by Omani artists and artists based in Oman. It is a compact stop, but a useful one if you want to see Muscat's current art scene rather than only forts, palaces, and older museums.
The gallery sits close to several Old Muscat sights, so it is easy to fold into a morning around the National Museum, Bait Al Zubair, and Al Alam Palace.
