 The guards of the citadel of Minas Tirith wear helmets of mithril, "heirlooms from the glory of old days".As a result, the citadel guards are the only soldiers in Gondor that still bear the emblems of the lost kings during the days of the stewards.As Aragorn's ships sail up the Anduin to relieve the besieged Minas Tirith during the War of the Ring, the standard flying on his ship shows a crown made of mithril and gold.
