The North Jutlandic Island (Danish: Nørrejyske Ø), Vendsyssel-Thy, or Jutland north of the Limfjord (Jylland nord for Limfjorden) is the northernmost part of Denmark and of Jutland. It is more common to refer to the three traditional districts Vendsyssel, Hanherred and Thy, however. The area has been intermittently a tied island, and during modern times was not surrounded by water until a storm of February 1825, which severed the region from the remainder of Jutland and caused a water connection between the North Sea and the western end of the fjord Limfjorden. Hence it is traditionally regarded as a part of Jutland rather than an island.
