The Prophet's Mosque in Saudi Arabia is known for its magnificent architecture and engineering wonders. One of the most remarkable features of this mosque is the moving domes. In this article, we will explore the enormous construction, exquisite decorations, and smooth motion of the King Fahd's expansion's domes. We will also discuss the automatic control system and the benefits of these moving domes.

The Moving Domes Design

The King Fahd's expansion of the Prophet's Mosque features 27 moving domes. These domes are installed on a square base with a side length of 18 meters and weigh 80 tons each. The iron axes they move on have a total length of 1,573 meters. The domes' internal structure is coated with layers of solid cedar wood, each with a thickness of 2 mm, and decorated with wooden shapes and pieces of blue turquoise. On the outside, the domes are covered with small hexagonal ceramic mosaic pieces with a diameter of 70 mm. They are decorated with geometric shadow lines in turquoise and light beige colors.

The Smooth Motion

The moving domes of the Prophet's Mosque are designed to move smoothly and quietly. The automatic control system opens and closes the domes at scheduled times. The domes move for only a few seconds, but this is enough to provide natural ventilation to the mosque and maintain a comfortable temperature for worshipers. The smooth and gentle motion of the domes is a testament to the advanced engineering and technology used in their design.

The Benefits of Moving Domes

The moving domes of the Prophet's Mosque serve several purposes. They help regulate the temperature inside the mosque, allowing worshipers to pray in comfort. They also provide natural ventilation and maintain a healthy airflow, reducing the risk of airborne diseases. Additionally, the domes' unique design adds to the beauty and grandeur of the mosque, making it a popular tourist attraction.
