As an island nation, the UK has a rich maritime heritage charting centuries of international trade and exploration. Evidence of this lies in abundance around the coastline in the form of historic shipwrecks. From 17th century remnants of Samuel Pepys navy off Goodwin Sands to bomb laden WWII liberty ships in the Thames estuary. Unlike land based heritage sites, the majority of these underwater locations are virtually invisible to the public gaze. Their inaccessibility limits public perception of their importance; out of sight, out of mind. In rare cases, e.g. the Mary Rose, the wrecks are recovered and placed in purpose built museums alongside artefacts recovered from them. The enormous cost of archaeological recovery, preservation and exposition restricts this practice.
