Jutland
The northernmost part of Jutland became an island following a flood in 1825; the Limfjord now separates it from the mainland. This island is called Vendsyssel-Thy or Nørrejyske Ø ("North Jutlandic Island") and is still commonly reckoned as part of the peninsula; it is also partly coterminous with the county and future region called North Jutland.
