The dome has an internal diameter of approximately 37 meters, making it one of the largest unsupported spans globally.
During the 1942 air raid, over 300 congregants were inside the church when the bomb fell through the roof.
The original unexploded bomb was defused by British bomb disposal experts and later discarded at sea.
Architect Giorgio Grognet de Vassé was a self-taught architect who faced significant controversy and local skepticism regarding his structural plans.
The church was constructed around the original, smaller parish church, which remained in use until the final stages of the rotunda's build.
The stone for the exterior was sourced primarily from local Maltese globigerina limestone quarries.
The rotunda's interior features a series of eight massive stone pillars that support the weight of the dome base.
The design intentionally mimics Roman neoclassical aesthetics, a rarity for 19th-century Maltese ecclesiastical architecture.
The Mosta Rotunda, formally the Sanctuary Basilica of the Assumption of Our Lady, is famous for its dome, which ranks as the third-largest unsupported church dome in the world. Designed by architect Giorgio Grognet de Vassé and modeled after the Pantheon in Rome, the church was completed in 1860. The structure is built on the site of a previous 17th-century church and features a massive portico with six Ionic columns. During World War II, a German bomb pierced the dome during mass but failed to detonate, an event locals consider miraculous. The interior is decorated with intricate paintings and gold gilding, including a replica of the bomb kept in the sacristy. The rotunda dominates the skyline of Mosta, serving as a primary spiritual and architectural landmark in central Malta. Visitors can access both the main church floor and the dome area, which offers views of the surrounding town and landscape.
