Shimal Fort, known locally as "Sheba's Palace", is an Islamic era fortification connected with the town wall of nearby Julfar, the Islamic era trading port and settlement. It was thought to have been the seat of the Ruler of Julfar. The
Wadi Sur town wall, running some 7km from the lagoon to the south of present-day Ras Al Khaimah to the mountains, was a 4–5m high defensive structure with watchtowers placed every 150 metres. The fort consists of a long rectangular structure located on a plateau overlooking the plain and settlement of Kush and, latterly,
Julfar. It has been dated to the 11th century, contemporaneous with the construction of the wall and the growth of Julfar as an important port, with
Kush as its administrative centre. In the 13th century, Kush was abandoned as the coastal area of Al Mataf flowered when Julfar became a tributary of the Kingdom of Hormuz. The town wall continued to be an important fortification until its collapse in the mid-18th century, while Sheba's Palace was relegated to the role of refuge fortification == See also ==
