In 1915, during World War I, when Malta was an important hospital base for the British and Commonwealth troops in the Mediterranean area, the Army built what was then called St. Andrew's Church Room. In 1932, plans for an extension to the Church Room were drawn up and funds were raised from civilians and supplemented by generous contributions from soldiers of both battalions quartered in Pembroke barracks. The church was known as the Christ Church Garrison Church. The service of dedication took place on Sunday 12 November 1933. The extension permitted over two hundred people to be seated comfortably. The building today houses the Athleta Sports Club at Burma Road.
