A 2009–13 joint study titled ''The Lyonesse Project: A Study of the Coastal and Marine Environment of the Isles of Scilly'' was commissioned by [[English Heritage]] and carried out by the Historic Environment Projects, [[Cornwall Council]], with a team of academics, local experts, and enthusiasts "to reconstruct the evolution of the physical environment of the Isles of Scilly during the [[Holocene]], the progressive occupation of this changing coastal landscape by early peoples, and their response to marine inundation and changing marine resource availability." The project found that while much of the story of Lyonesse can be "dismissed as fantasy", an overflow of legends and memories of submergences is common throughout the northwestern portion of Europe. It concluded that the Isles of Scilly were once a single large island, which separated into smaller islands due to the rapid sea-level rise. Stone walls have been located under the water in the vicinity of the Isles of Scilly, which support the findings that sea level rises impacted the towns of the area, although whether they are evidence of buildings or the remains of medieval fish traps remains unclear.<ref>{{cite web|url=https://archaeologydataservice.ac.uk/archives/view/lyonesse_eh_2014/overview.cfm|work=Archeological Data Service|title=The Lyonesse Project: a study of the coastal and marine environment of the Isles of Scilly|first1=Dan|last1=Charman|first2=Charlie|last2=Johns|first3=Kevin|last3=Camidge|first4=Peter|last4=Marshall|first5=Steve F|last5=Mills|first6=Jacqui|last6=Mulville|first7=Helen M|last7=Roberts|date=2014|access-date=13 May 2021}}</ref>
