Muscat – This makes it the most suitable location for the construction of a large mosque after the Sultan Qaboos Grand Mosque in Muscat, in terms of size and area.

Inaugurated on September 18, 2015, the mosque’s design draws inspiration from the authentic architectural traditions of the region, emphasizing simplicity, elegance, and a harmonious integration with the surrounding environment. What sets the mosque apart is its four towering minarets – each rising 80 meters – giving it a distinctive silhouette among the religious structures of Oman.

Strategically located at the crossroads connecting Nizwa to Muscat, Salalah, and Bahla, the mosque sits on an 8,000-square-meter site adjacent to Wadi Nizwa, elevated to protect against flooding and to enhance visibility across the city. This location is part of a broader urban planning initiative aimed at modernizing Nizwa while preserving its cultural essence.

The mosque’s main prayer hall, measuring 60 x 60 meters, covers an area of 3,546 square meters and accommodates around 4,500 worshippers. The space is entered from the Qibla side via a grand staircase and through a covered courtyard, with additional access points from the landscaped gardens to the north and south. Surrounding the hall are two open-air courtyards and a covered courtyard, expanding the mosque’s total capacity to over 9,800 worshippers during peak times.

The mosque also features a women’s prayer hall that holds up to 434 worshippers, with dedicated entrances ensuring privacy and accessibility. Supporting facilities such as ablution areas, administrative offices, and service rooms are located on the ground floor, raised five meters above ground level. Equipment and technical infrastructure are housed on a service floor above the main hall.

Architecturally, the mosque features a central dome measuring 27 meters in diameter and rising 55 meters above ground, with ornate finishes inspired by traditional Omani design. The interior boasts decorative marble, intricately engraved Qur’anic inscriptions, and colorful glasswork. The mihrab, in particular, is a highlight of Omani craftsmanship, featuring geometric and floral motifs rendered in marble inlay.

Among the mosque’s key facilities is the Sultan Qaboos Mosque Library, operated by the Sultan Qaboos Higher Centre for Culture and Science. Spanning 277.5 square meters across two floors, the library surrounds a glass-covered internal courtyard and houses Qur’an memorization classrooms, a multi-purpose hall equipped with audiovisual systems, and reading spaces that serve both spiritual and educational purposes.
