Limfjorden

The Limfjord cuts across northern Jutland through broad basins and narrow, shallow channels. For much of the early modern period a sand spit separated its western end from the North Sea, leaving the eastern entrance at Hals as the principal route to the sea. Its brackish waters supported important fisheries, while the shallows at Løgstør made navigation difficult. In 1825 a storm breached the spit at Agger; ships could use the new passage from 1834.
