Located on Queens Avenue in Aldershot, England, the building was originally intended to be the principal church for the Anglican chaplaincies of the British Army but since 1973 it has been the seat of the Roman Catholic Bishop of the Forces.

The church was designed in 1892[1] in the Early English Gothic Revival style by Ingers Bell and Aston Webb[2] of the War Office.

Because the building was originally intended as the principal church for the Anglican chaplaincies of the British Army, the foundation stone was laid by Queen Victoria on 27 June 1892.

[6] The ornate east end, with a rich 1930s mosaic on the reredos portraying the Last Supper, contrasts with the simplicity of the rest of the chancel, which was reordered to provide room for a free-standing plain altar.

The East Window over the altar is dedicated to the men of the Royal Army Service Corps who lost their lives during the Boer War of 1899–1902.

The window depicts The Ascension, The Translation of Elijah, The Crucifixion, Moses and the brazen serpent and Samson carrying off the Gates of Gaza.

The Allen organ currently used in the cathedral originally belonged to the noted organist Carlo Curley and was obtained in 2014 after his death.

Constructed by Yorkshire-based blacksmith Chris Raw, the crucifix was described as "a fitting and deeply significant link to those of us who serve in the Royal Air Force and our colleagues who went before us especially those who lost their lives in the service of their country.
