The lower lighthouse, known as the Plover Scar Lighthouse, (sometimes called Abbey lighthouse) still stands on Plover Scar, and it remains operational. The old high light, a square wooden tower, was demolished in 1954; but the former keepers' cottage, built alongside the high light, can still be seen. Lancaster (and hence also Lancashire) is named after the Lune. The name of the ancient hundred of Lonsdale is also derived from the river. The river

It is the location of Shannon Airport, an international airport serving the Clare/Limerick region in the west of Ireland. Shannon is a new town. Spearheaded by Brendan O'Regan, it was built in the 1960s on reclaimed marshland alongside Shannon Airport, along with the Shannon Free Zone industrial estate.
