The building occupies the north side of Crown Square and the highest site in the Castle, but rather than intrude something wholly new on the historical character of the place, on three sides the architect has used the walls of the original barrack block. The fourth side, the entrance from Crown Square, is however a completely new façade with a high central porch and projecting wings, but even so the new stonework is integrated with the old as the rubble construction of the old building continues in the new, a theme of historical continuity that is carried through the whole building.
Correspondingly, the ashlar and stone cut of the porch and sculpture on the newly built façade continue on the decorative features that have been added to the old walls right around the building, including the gothic construction of the apsidal shrine which projects from the north wall.
Although this is church-like in form, the building's layout and detailed iconography, certainly deeply spiritual, are nevertheless deliberately not religious in the sense of being specifically Christian.
Whichever direction you approach it from, the iconography of the Memorial engages you and it is sustained throughout with remarkable consistency, a tribute to the co-operation that brought the whole thing about. As it stands however it is also the case that though the Memorial contains the names of those who have fallen in subsequent wars, its design and iconography are the product of the experience of the First World War 1914 - 1918.
