Fort al-Jalali or Ash Sharqiya Fort is a fort in the harbor of the old city of Muscat Oman. The fort was built by the Portuguese in the 1580s to protect the harbor after Muscat had twice been sacked by Ottoman forces. It fell to Omani forces in 1650. During the civil wars between 1718 and 1747 the fort was twice captured by Persians who had been invited to assist one of the rival Imams.
