Historical Background
The Mosta Rotunda, officially the Sanctuary Basilica of the Assumption of Our Lady, is one of Malta’s most iconic churches. Built between 1833 and the early 1860s, it replaced an earlier parish church dating back to around 1614.
The parish of Mosta itself became formally established in 1608 following documentation by inquisitor Pietro Dusina in 1575. This growing community eventually required a larger church, leading to plans for the present magnificent structure.

Architecture and Design
Designed by neoclassical architect Giorgio Grognet de Vassé, the Rotunda’s design is inspired by the ancient Pantheon in Rome, featuring a circular plan and a grand unsupported dome.

The dome measures approximately 39.6 metres internally, supported by massive walls more than 9 metres thick. At the time of its completion, it was among the largest unsupported domes in the world.
The façade features a classical portico with six Ionic columns flanked by two bell towers, while the interior is spacious and lit by natural light from the dome above. Beneath the church lie extensive World War II air-raid shelters.

Construction Timeline
- 30 May 1833 – Foundation stone laid amidst debate over the innovative design.
- Early 1860s – Main construction completed after nearly three decades.
- 15 October 1871 – The church was formally dedicated.

The Miracle Bomb – World War II
One of the most famous events associated with the Rotunda occurred on 9 April 1942 during World War II. A German aerial bomb pierced the massive dome during Mass, where around 300 worshippers were gathered, but miraculously it did not explode. Local people regarded this as a miracle.

A replica of this historic bomb is now on display inside the church’s sacristy under the inscription Il-Miraklu tal-Bomba, 9 ta’ April 1942, commemorating the event.

Religious Significance
The Rotunda is dedicated to the Assumption of Mary, a central feast in Maltese Catholic devotion. Its annual feast is celebrated on 15 August, drawing parishioners and visitors for processions, liturgies, and cultural festivities.

In 2018, the church was elevated to the status of a Minor Basilica by Pope Francis, reflecting its importance as a centre of worship and heritage.

Visiting the Rotunda
Today the Mosta Rotunda remains an active parish church and major tourist attraction. Visitors can admire its grand interior, explore WWII air-raid shelters beneath the church, and view the bomb replica that symbolizes miraculous survival. Regular Masses, tours, and feast-day events make the Rotunda a living cultural landmark.
