This exquisite rotunda inside the Church of the Assumption of Our Lady is both beautiful and massive. Its diameter is 122 feet and the ceiling walls are 30 feet thick. This makes it one of the largest in the world. It is also responsible for deflecting two bombs dropped by German aircraft on April 9, 1942. A third bomb pierced the dome while perishers were praying inside but did not explode. A replica of this World War II bomb can be found in the back of the church. It is appropriately called “The Bomb Miracle.”
