Illustration Nizwa Fort. This is visually the most impressive of all the Omani forts, as it has a huge round tower that dominates the surrounding landscape. It was built by Sultan bin Seif over three hundred years ago after he had evicted the Portuguese from Muscat. The fort took twelve years to build and reportedly cost eighty thousand crowns. Nizwa has always been considered the key possession for anyone aspiring to control the old Oman and for many years was the Imamate capital.
