Historians can not agree on the origins of the name of the city. Some suggest the name was derived from the Arabic verb which means being alone. Others say that the city was named after an old water spring.
Nizwa was the capital of Oman in the 6th and 7th centuries AD. With its deep connection to the root of Islam, Nizwa possesses a number of renowned mosques, such as Sultan Qaboos Jama (Friday mosque), So'al Mosque built in the 2nd century AH (9th century AD), Ash-Shawathinah Mosque in Uqr and Ash-Sharja Mosque. There are also Al-Ain Mosque, Ash-Sheikh Mosque and Shuraij Mosque in Tanuf built in 377 AH (around 1,000 AD).
In the early 1950s the large round tower of the ancient fort built around 400 years ago in the center of the town was bombed and rocketed by the British Royal Air Force who were called in to assist the then reigning Sultan, Said bin Taymour in suppressing a revolt by leaders of the interior Imamate of Oman. The conflict was driven by a struggle for shares in the newly discovered oil wealth.
Nizwa has become a more modern city since 1970 under the reign of Sultan Qaboos. Improvements include connections to Muscat via a two-lane highway which has increased tourism. Communications have been improved to include broadband access and there is a substantial hospital. It is also a hub for education including a Technical College, College of Applied Sciences, The University of Nizwa, and the training academy for the Royal Oman Police. There are now four hotels and tourism is promoted in the area
