Marine Scotland work with Historic Environment Scotland (previously Historic Scotland) to identify and designate Historic Marine Protected Areas (HMPAs).
HMPAs are designated in Scottish territorial waters (0-12 miles) under the Marine (Scotland) Act 2010 for the purpose of preserving marine historic assets of national importance.
Historic MPAs are normally considered appropriate for protecting underwater heritage, for example a particularly significant historic shipwreck, remains relating to an important fleet anchorage, battle site or navigational hazard where multiple wrecks and other features exist. It would also be possible to designate a submerged prehistoric landscape if structural or artifact-based evidence is identified on the seabed.
Other forms of statutory designation also help to protect cultural heritage sites around the coast of Scotland.
