The Sunken Lands were said to lay between Britain and Ireland, and figure in an episode of the Mabinogeon. Interestingly, that cycle starts before there were tides. :') Another lost land off Britain is Lyonnesse. Still another is off the Solent. Axeheads have been dredged up off the floor of the North Sea. There's a lot of stuff down there.
