Seventy five years ago, in January 1947, the Liverpool Daily Post described plans for a new defence scheme to protect East Rhyl from the sea at a cost of £160,000, to include an extension of the promenade. The article stated that “Two and a half miles of sea front is protected by the promenade. The erosion has taken place at the end of the promenade because the sea, unable to make any inroads into the concrete sea wall, has taken advantage of the first weak spot.”
Mr T. Lomax, surveyor to the Urban Council was afraid of the consequences if the new scheme did not begin immediately. He said ” between 1871 and 1945 the high water mark had advanced 1,500ft” (457 metres). When asked what the effect the new promenade would be on Prestatyn, which has practically no form of sea defence, Mr Lomax said “The promenade will go right to the Rhyl-Prestatyn boundary. If Prestatyn does not proceed with a scheme the sea will cause considerable erosion at the end of the new wall, just as it had done for years at the end of the old promenade.”
Work to protect East Rhyl from the sea is, of course, being carried out today and lots of information about this can be found by clicking here.

Before WW2 dad was a plubmers apprentice and fitted a toilet at Salem Cottage by Rhyl golf course. He told me that many people has commented about the bungalow and the never ending fight of building and rebuilding walls to stop the sea encroaching. When he returned from the war, he worked on the sea defences and noted that the toilet he fitted was still standing but then majority of the property had been engulfed by the sea. The amount the sea encroached in those 74 years from 1871 is astonishing.

Fascinating. Thanks Ruth 😊
