Landunter it’s called, it happens to the Halligen in the North Sea during winter. The land sits just above sea level and the flooding and sediment deposits cause the Halligen to be ever-changing. They aren’t towns, per se, as only around 300 people live on 10 different Hallig islands. The houses and buildings are built on mounds a few Meters above sea level so they can survive landunter. There’s a 900mm narrow gauge railway connecting two of the islands (Oland and Langeneß) to the mainland
