Dibba Al-Hisn

Dibba Al-Hisn (, "white Dibba") is a pene-exclave of the emirate of Al-Sharjah, one of the seven United Arab Emirates. It is bordered by the Gulf of Oman from the East, Dibba Al-Baya (a province of Oman in Musandam) from the North, and Dibba Al-Fujairah from the South. It is also geographically part of the Dibba region. It is the smallest in size among the Dibbas. It is mostly known for its fish market and the ancient fortress from which it got its name. Also, it is known for its high density of population relative to the other Dibbas.
History.
Pre-Islamic period.
Dibba Al-Hisn has been an important site of maritime trade and settlement since the pre-Islamic era. Although there is slight information, mainly from tombs, of settlement during the later second millennium and early first millennium BCE, contemporary with such sites as Shimal, Tell Abraq and Rumeilah, and of scattered occupation during the period of al-Dur and Mileiha, most mention of Dibba is in the period just prior to and after the coming of Islam. Under the Sasanians and their Omani clients the Al-Juland, an important market existed at Dibba. Dibba was sometimes the capital of Oman. According to Ibn Habib, "merchants from Sindh, India, China, people of the East and West came to it."
Colonial period.
Portuguese occupation (1624 - 1648 CE).
Dibba Al-Hisn is believed to be the site where the Portuguese during the Habsburg Dynasty built a fort and a wall around the city. In August 1648, the Arabs besieged Muscat, Oman, and on October 31, 1648, a treaty was signed between the two opponents. The terms required the Portuguese to build the fortress of Kuriyat, Dibba Al-Hisn and Matrah (Oman).
