Muscat Gate Museum The Muscat Gate Museum is one of the places to visit in Oman. It has everything about Oman’s history as early as the Neolithic era up to today. That is somewhere between 10,200 BC to 2,000 BC. It is located in Al Saidiya Street and is being supervised by the Ministry of Defence. The Muscat Gate Museum was operational since January of 2001 and it has a lot of special exhibits. Actually, the gate itself is the attraction as it divides the Muscat proper and the old city.
