The larger arches on the main axis form a coffered, barrel vault ceiling, crossed by the lower arches to either side. The main axis is aligned so the sun would have been at its centre at sunrise on Armistice Day, 11 November (trees and buildings to the south have lowered the apparent horizon since the memorial was built, meaning the sun appears to be slightly off-centre). Four painted stone flags are set inside the archway, raised on corbels on the inside of the legs: the Union Flag (representing the British Army) and the flag of the Royal Navy (the White Ensign) at the front, and the flags of the Merchant Navy (the Red Ensign), and Royal Air Force (the Royal Air Force Ensign) at the rear.[1][18] Painted stone flags are a recurring feature in Lutyens' war memorial designs; he first proposed them for the Cenotaph, where they were rejected in favour of fabric, though they feature on several of his other designs besides Leicester (other examples include Northampton War Memorial and Rochdale Cenotaph).[19][20][21]
