The metropolitan area spans approximately 580 square miles and includes six wilayats. Known since the early 1st century CE as an important trading port between the west and the east, Muscat was ruled by various indigenous tribes as well as foreign powers such as the Persians and the Portuguese Empire at various points in its history. A regional military power in the 18th century, Muscat's influence extended as far as East Africa and Zanzibar. As an important port-town in the Gulf of Oman, Muscat attracted foreign tradesmen and settlers such as the Persians, the Balochs and Gujaratis.

Khasab is a city in an exclave of Oman bordering the United Arab Emirates. It is the local capital of the Musandam peninsula and has frequently been dubbed the "Norway of Arabia" because of its extensive fjord-like craggy inlets and desolate mountainscapes. The Portuguese built Khasab at the beginning of the 17th century, at the height of their naval presence in the region. The natural harbour gave shelter from tough seas. Unlike many forts, which were built on high ground for defensive purposes, Khasab was designed as a supply point for dates and water for Portuguese ships sailing through the strait. Today, Khasab is protected from floods by three large dams.
