That's the story of the Netherlands. Entire cities and even islands have disappeared under the sea. Humans always rebuild.

I would argue lost cities are a story in the margins of the story of the Netherlands. The main story would be a move from building towns on little hills that don't get flooded most of the times to building systems to actively manage water (wind- and steam-powered pumps) and flood defenses (Afsluitdijk, Deltaworks). Netherlands never had as much land as it has now so the balance is definitely on reclaiming rather than losing.
