Mosta Dome, meaning the church in Most, exactly the Roman Catholic Church of the Assumption of the Mother of God, called the Rotunda in Most. The temple has a dome with an internal diameter of 37.2 m - the third among the largest unsupported domes in Europe and the ninth in the world. The church is also famous as the site of the Miracle Bomb.
On April 9, 1942, during the Luftwaffe air raid, two 50-kg bombs hit the dome of Mosta Dome - one bounced and fell next to the church, the other pierced the dome and got inside the temple, in which there were about 300 believers. There was no tragedy because the bomb did not explode. Currently, a bomb of the same type (the original has been sunk) with the inscription: Miracle of Bombs is displayed in the vestibule of the church.
The Mosta Dome church was built in 1833-1860 (consecrated in 1871) according to the design of the Maltese architect Giorgio de Grognet Vassé. Its walls, formed in the shape of a rotunda, are 9 m thick, necessary to maintain the giant dome.
