It stands where the NE corner of the modern inner harbour (marina) will be constructed. Locals pay 1lb of candle wax to take their horses & carts across the bridge for the upkeep of the 'Lady Licht'. This is a red candle which shines from a chapel window to guide seafarers & may be the origin of Arbroathians being nicknamed 'Red Lichties'.
