The arms of the College are a differenced version of the royal arms of the founder King Edward II, namely the three gold lions of the Plantagenet arms on a red background.
The long-time informal emblem of the Tortoise Club (1st Summer VIII and 1st Torpid crews), was formalized in a grant to the College by Letters Patent dated 20 April 2009 of Garter, Clarenceux and Norroy and Ulster King of Arms.
