Ras Hafun is home to numerous ancient structures and ruins. The peninsula is believed to be the location of the old trade emporium of Opone. The latter is mentioned in the anonymous Periplus of the Erythraean Sea, written in the first centuryCE. Opone is described therein as a busy port city, strategically located on the trade route that spanned the length of the Indian Ocean's rim. Merchants from as far afield as Indonesia and Malaysia passed through the settlement. As early as 50 CE, the area was well known as a center for the cinnamon trade, along with the barter of cloves and other spices, ivory, exotic animal skins and incense. In the 1970s, a Somali-British archaeological expedition in Hafun and other parts of northern Somalia, led by Neville Chittick, recovered numerous examples of historical artefacts and structures, including ancient coins, Romanpottery, drystone buildings, cairns, masjids, walled enclosures, standing stones and platform monuments. Many of the finds were of pre-Islamic origin and associated with city-states and trading centers described in ancient documents. The Damo site, in particular, was suggested by Chittick to correspond with the Periplus' "Market and Cape of Spices". Some of the smaller artefacts that the company found were subsequently deposited for preservation at the British National Museum. A later expedition in Hafun, led by an archaeological team with the University of Michigan, excavated Ancient Egyptian, Roman and Persian Gulf pottery. In the 1980s, the British Institute in Eastern Africa also recovered pre-Islamic Partho-Sassanid ceramics from the peninsula, which were dated to the first century BCE and the second through fifth centuries CE. Archaeological excavations at the western Hafun site have yielded ceramics from ancient kingdoms in the Nile Valley, Near East, Persia and Mesopotamia, as well as some sherds of possible derivation from the Indian subcontinent. Among this ware is a late Ptolemaic lamp fragment, Parthian glazed sherds, and Hellenisticlagynos wares. Smith and Wright have dated the finds to sometime between the 1st century BCE and the early first century CE. Additionally, some ceramics affiliated with green glazed ware from Sohar on the Omani littoral have also been found in the area. These pieces have been dated to between the 1st century BC and the 5th century BCE. Hafun is also home to an ancient necropolis. Similar historical structured areas exist in various other parts of the country.
During the pre-independence period, Hafun was governed by the Majeerteen Sultanate and was the seat of the polity's capital, Alula. It later formed a part of Italian Somaliland, when the area was known as Dante. In December 2004, Hafun was struck by a tsunami caused by the 2004 Indian Ocean earthquake. It was the most affected area on the continent, and the only location west of the Indian subcontinent where the waves pulled away from the shore before rushing in.
