The Church of Our Lady of Atocia in Hamrun was built in 1630, to replace a small medieval church nearby, dedicated to St Nicholas which was abandoned and declared profane in 1575.

The Church of the Immaculate Conception in Msida was built in thanksgiving by sailors who were saved from captivity by Turks. They dedicated the church to ‘Our Lady of Perpetual Help’.

The Parish church of Hamrun was built between 1869 and 1875, to designs by the Maltese architect George Schinas (1834-1894).

The Parish church of St Gregory the Great in Sliema is a modern church, built between 1923 and 1940, to the design of the Maltese architect Godwin Galizia (1880-1944).
