Khasab is a city in an exclave of Oman. It is the local capital of the Musandam peninsula. Khasab is located 500 kilometers (310 mi) from Muscat and is dubbed the "Norway of Arabia". The Portuguese built Khasab at the beginning of the 17th century at the height of their naval presence in the region. The natural harbor 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.
