The name of this town is a derived from the Middle Iranian rōstāg, meaning "district" (also in Baluchi, Persian, Kumzari, etc.), New Iranian rusta, meaning a 'large village.' The term is a cognate to other Indo-European tongues such as Latin, where 'rustica', means the same thing (whence the source for the English term, 'rustic').

Rustaq is located amidst the Hajar Mountains, and they surround the city from all directions except the northern side. This northern side is the direction from which the city opens up to the coastal regions in the area of Al-Batinah (including Al-Musannah and Al-Suwayq), which is the most active and important vital passage in the region. It is also considered a link connecting the city to the Omani capital, Muscat, which is only 160 km away. Rustaq is also distinguished by its rocky and sandy desert environment in the northeastern direction.

During the days of the Sasanian Empire, Al-Rustaq had a Persian marzban (military governor), whom Sasanians in the area would report to. Dibba and Tuwwam, which Oman today shares with the U.A.E., were taxed by Al-Julanda, who were clients of the Sasanians. There are also historical mosques in Rustaq, including Al-Bayada Mosque, the Basra Mosque, and the Qasra Mosque.

Rustaq Fort, built four centuries prior to the 7th century C.E., is an imposing structure built on three levels, containing separate houses, an armoury, a mosque and four towers. The tallest tower stands over 18.5 m (61 ft) high, and has a diameter of 6 m (20 ft).

The Rustaq Castle [ar] (Arabic: قَلْعَة ٱلرُّسْتَاق, romanized: Qalʿat Ar-Rustāq) is located on the slopes of the Green Mountain at the edge of the Batinah plain in the Rustaq province of South Al Batinah Governorate. The castle was initially built on Persian ruins around the year 1250 AD, but the impressive current structure was rebuilt by the first Imams of the dynasty of Ya'Aruba during the period from 1624 to 1649 AD. It consists of two main floors in addition to the ground floor, featuring residences, weapon storage rooms, reception rooms, gates, a mosque, prisons, wells, and other facilities.

The second tower is the "Wind Tower," built by Imam Saif bin Sultan Al Ya'arubi, whose tomb is located in the western corner of the castle. The "Wind Tower" reaches a height of 12 meters and has a diameter of 12 meters as well, with a hundred decorative triangles surrounding its walls.
