Further Information

This rock was removed from the hull of HMS Pique in 1835. The ship had previously run aground whilst patrolling off Labrador and still managed to sail across the Atlantic with the rock in place.
 
There is no mention of the origins of the rock at it's current location. The only information concerning the rock is on an information board at the other end of the Porter's Garden.
 
HMS Pique was a fifth rate of 1633 tons launched in 1834. The engraving of the ship as she was seen at Spithead in 1836 is held by the National Maritime Museum.
