Movable Domes: Architectural Masterpiece Adorning Prophet's Mosque

Among the most striking features of the grand Saudi expansion of the Prophet's Mosque are the 27 movable domes, an architectural marvel that reflects the Kingdom’s dedication to serving Islam and Muslims. The expansion, launched during the reign of the late Custodian of the Two Holy Mosques King Fahd bin Abdulaziz, began with the laying of the foundation stone in 1405 AH.
 Weighing approximately 80 tons each, the movable domes are a unique feat of engineering that seamlessly blends robust construction with smooth mobility. Positioned on square bases measuring 18 meters on each side, the domes glide along 1,573 meters of iron rails using an automated system that enables fluid opening and closing. The dynamic design contributes to enhanced airflow, optimal sound distribution, and a soothing atmosphere within the mosque.
 The domes were meticulously designed to adapt to weather conditions, ensuring the comfort of worshippers throughout the year. Their interiors feature solid cedar slats inlaid with turquoise pieces, while the exteriors are adorned with ceramic tiles, sandy and turquoise hues, and finely etched shadow lines. Geometric windows allow natural light and air to filter into the mosque, further enriching the spiritual experience of visitors.
 Each dome is also embellished with Quranic verses and intricate Islamic calligraphy, reinforcing the mosque’s spiritual and aesthetic identity. As part of a comprehensive maintenance program for the Prophet’s Mosque, the domes undergo regular upkeep to preserve their structural integrity and architectural beauty.
