What is "muttrah"

Muttrah, administratively a district, is located in the Muscat province of Oman. Before the discovery of oil, Muttrah was the center of commerce in Oman (Muscat). It is still a center of commerce as one of the largest sea ports of the region is located there. Other landmarks include Souq Muttrah, a traditional bazaar and Sour Al-Lawatiah, a small community of houses surrounded by an old wall. To the south lies Muscat District.
