Explore Mosta: the Rotunda's Unexploded Bomb & Great Dome

On 9 April 1942, during one of the heaviest Luftwaffe raids of the Siege of Malta, a bomb pierced the Rotunda's dome directly above a congregation of several hundred people attending Mass. It skidded across the church floor and failed to explode — no one inside was harmed, an outcome the town has regarded as a genuine miracle in the decades since. A replica of the bomb is displayed inside the church, and the story remains central to Mosta's identity, told to every visitor who asks about the dome above them.

Built between 1833 and 1860 in a Neoclassical style modelled directly on Rome's Pantheon, the Rotunda's dome ranks among the largest unsupported domes anywhere in the world — a genuine feat of nineteenth-century engineering achieved without the steel reinforcement modern domes rely on. The church dominates Mosta's skyline from every approach road, and the interior — vast, circular, lit from an oculus at the dome's crown — is free to enter, with the bomb story adding a layer of genuine local reverence to what would already be an architectural landmark.

Mosta's Feast of the Assumption each August ranks among Malta's biggest village festas — statue processions, marching band clubs and fireworks fill the streets around the Rotunda for days, a genuine expression of the parish pride the church commands year-round. On the town's edge, Wied il-Għasel (the Valley of Honey) is a limestone gorge with walking paths and a small chapel cut into the rock — a quieter, greener counterpoint to the church's grandeur, reachable in minutes from the town centre.
