The heraldic window in this alcove is surmounted by the crown and the English royal motto: Dieu et mon droit.. It is one of the very few places in the Palace where a symbol is shown for the Principality of Wales: the red dragon at the bottom centre. Beneath the window, a glass case contains three volumes commemorating the 408 peers, Lords of Parliament and Officers of the House of Lords who laid down their lives in World Wars One and Two.
