On the first floor of Bait al Bagh is the Mohammed Al Jamali Gallery, which features a stamp collection from across the world and on the beautiful mezzanine floor there is the Omani Gallery of Stamps where one can see numerous examples of Omani flora and fauna as well as trace the history of Oman and its postal system from the late 1800s to the present day.  Muscat and Oman first used the stamps of India, then Pakistan, then the British Postal Agencies in Eastern Arabia, before finally issuing its own stamps as the Sultanate of Oman on 16 January 1971.
