The remains of a cargo vessel, thought to date after 1627, which foundered west of the Outer Pollock Reef, off West Bay. Cannon from the site indicate that she was may have been armed; a bronze gun is thought to date between 1627 and 1750 at the latest, although clearly 1750 is not a terminus ante quem for the date of the wreck. An alternative interpretation is that the guns were scrap metal. She is thought to have been laden with iron bars and with ballast thought to have originated in south-western England or northern France.


Assessment in 2005 determined that the site consists of a low mound of heavily concreted iron bars containing a heavily concreted iron gun as well as a possible seventeenth-century muzzle-loading bronze gun of European or Eastern origin. The remains lie in approximately 12m of water and the surrounding seabed comprises generally fine sand although the iron bar mound lies on an area of large cobbles.

Analysis of hard slate and quartzite (ballast?) samples recovered from this area suggests a derivation from south-west England or Northern France. The presence of the large quantity of iron bars does suggest that they formed part of a cargo and it is thought that the site may comprise the remains of a merchant vessel. The dating of the site is reliant on the bronze gun which is considered to be no later than 1750, but perhaps as early as 1627.


Designation History: Designation Order: No 1974, 2005 Made: 17th July 2005 Laid before Parliament: 19th July 2005 Coming into force: 20th July 2005 Protected area: 50 metres within 50 42.244 N 002 46.708 W

No part of the restricted area lies above the high-water mark of ordinary spring tides.

Documentary History: The identity of the wreck is currently unknown and the known documentary evidence does not provide a good match for the identity of this vessel as there is little matching evidence. (2)

Archaeological History: The wreck was discovered in 2004 by recreational divers from a local sub-aqua club diving on the reef and reported to the Dorset Coast Forum. The following year, assessment concluded that the wreck is most likely seventeenth-century (with dating being reliant on a bronze gun in situ), thought to date from as early as 1627 and no later than 1750. The date is thought unlikely to fall outside the range 1550 to 1750 if the guns found were carried as armament, although the range can be extended forward 100 years to c.1850 if they were cargo. The bronze gun is thought to be a falcon and was probably cast in the period 1550 to 1700 and is of European or eastern origin.

A large quantity of iron bars found on the site indicates that they were cargo, and the remains may therefore represent a cargo vessel, or be a cargo dump. The relative disposition of the iron bars suggests that they are still in the same relative position as when packed in the vessel, suggesting that they were lost with the vessel, rather than jettisoned in extremis. Some hard slate and quartzite samples from the gravel within the mound may represent ballast.

The wreck is thought to have been lost as a result of being embayed on a lee shore, or attempting to enter or depart West Bay Harbour in adverse weather conditions.

The site may have been more deeply buried in the past, supported by the fact that the local diving community appeared to be unaware of the wreck until 2004. The uncovering of the site may be due to any or all of the following factors: a step change in the level of the sand to the north-east, modern onshore activity such as recent harbour improvements, and exceptional storm waves causing short-term erosion.
