I attended Winterdyne School from September 1949 to July 1956. The School was at 5 Waterloo Road, Southport; the building has now completely gone. If you want to see what the site looks like now, click here (let me know if I’ve got it wrong).
These pages are going to hold some memories of the school. There is already a Facebook group for those of us who attended the school at various times. You can find it at https://www.facebook.com/groups/101399264915/?fref=ts.
The motto of the school shown in the badge means ‘Pray and work’. There is a Wikipedia article on the subject.
For interest, here are extracts from two inspection reports dated 1943 and 1957.
