Seen from almost anywhere in Mosta, the dome rises above the rooftops like a grey-green hill that someone has put a cross on. Up close, from Rotunda Square, it is bigger than expected, and the approach between the two bell towers is the best view of it.
A dome with a Roman model
The Mosta Dome, also known as the Rotunda of Mosta for its round form, is the town’s symbol. The dome is 37 metres in diameter, one of the biggest in Europe, and it is said to rank ninth among the largest unsupported domes in the world.
The official name is the Church of the Assumption. It is dedicated to the Assumption of Mary, who is the patron saint of Mosta. According to Catholic tradition, the Virgin Mary was taken up into heaven at the end of her earthly life, and the church was built in her honour on the central square.
Grognet de Vasse and the Pantheon
The architect was Giorgio Grognet de Vasse, a local man. He took inspiration from the Pantheon in Rome and recast the idea in a neo-classical style. Because the design came from an ancient temple, the official church in Malta did not approve the project, and he had to build the church at his own risk, using his own funds and the support of Mosta residents.
The first stone was laid in 1833, and construction lasted 28 years. A particular difficulty was that the new church had to be built around the old one, a seventeenth-century building that had become too small for the growing parish. After the dome was finished, the old church was demolished, and the new one was praised as a masterpiece.
The bomb
The best-known story of the church dates from the Second World War. A 500 kg German bomb fell through the dome during mass, when about 300 people were inside. It broke a hole in the marble floor but did not explode, and nobody was hurt.
The event was interpreted as a miraculous intervention, and a copy of the bomb can be seen in the sacristy. Ask a member of staff if you cannot find it. The story is told here with great seriousness, and it is part of the reason the church draws visitors beyond those interested in architecture.
The interior
Inside, the space is the main event. The dome seems to float, helped by the soft light colours of the walls and ceiling and by the light from the windows. The interior holds paintings, statues, stucco moulding and gilded and carved details. It is a big space, and standing in the middle of the floor and looking up is a good way to understand the scale of the building.
The façade has two bell towers and is decorated with arches, columns and niches that contain statues of saints. It gives photographers a good backdrop, and the square in front provides enough room to stand back.
Mosta and its neighbours
Mosta itself is a busy town, and the square has cafes that make a pleasant place to sit after your visit. Nearby, the Palazzo Parisio gardens, the Ta’ Bistra Catacombs and the Wied il-Ghasel valley give options for the rest of the day. The Victoria Lines pass close to the town as well, with Mosta Fort among the surviving structures.
A reasonable plan is to visit the Dome in the morning, have a coffee in the square and then choose between the gardens and a walk in the valley.
Seeing it from the square
Stand in the middle of Rotunda Square and turn slowly. The dome is visible from nearly every angle, and the streets radiate out from the church like spokes. This is a town planned around a monument, and the effect is strong at dusk, when the dome is lit and the cafes fill.
The scale of the building also explains the story of the old church, which stood inside the new walls while the dome was raised. Imagine the congregation worshipping in a smaller building while a giant shell grew around them for twenty-eight years.
Practical points
Dress modestly: shoulders and knees covered. The Dome is a working church, and services take priority. Quiet is expected, and photography rules may vary.
Midday is the busiest time because of tour groups, so early morning or late afternoon is calmer. Pavements around the square are flat and easy. Combine the visit with lunch in Mosta, and keep an eye on the clock if you want to go inside, since churches often close for a break in the middle of the day.
