The memorial forms a hemispherical half-dome about high, with 240 panels divided into five sectors, with five rectangular windows of painted coloured glass, each of which features a personification of one of the virtues – Truth, Hope, Justice, Fortitude and Faith. The dome is replete with classical and religious symbolism, featuring a winged figure of Victory stepping from a boat into a classical temple, accompanied by Roman soldiers, putti, a dove symbolising peace, the Royal coat of arms of the United Kingdom, and armorial shields and badges for the territories of the British Empire. Two panels, one to either side, list battles in the First World War – Cambrai, Mezières, Arras and Lens, Galipoli, and Messines Ridge to the left; and Bethune, Salonika, Ypres and Loos, Givenchy, Paschendaele to the right. The glass was put together by Lowndes &amp; Drury at The Glass House, Fulham. It was unveiled by General Sir Herbert Alexander Lawrence on 1 June 1922, and dedicated by the Bishop of Willesden William Perrin. It replaced clear glazed windows and dome included on the north side of the exchange when it was rebuilt in 1903. Originally, it was accompanied by marble panels listing the 61 dead, which had been installed earlier and unveiled on 16 July 1920.
