The present-day Sultanate of Oman lies in the south-eastern Arabian Peninsula. There are different definitions for Oman: while traditional Oman also includes the present-day United Arab Emirates, its prehistoric remains differ in some respects from the more specifically defined Oman proper, which corresponds roughly with the present-day central provinces of the Sultanate. In the north, the Oman Peninsula is more specific, and juts into the Strait of Hormuz. The archaeology of southern Oman Ẓafār develops separately from that of central and northern Oman.
