I only add an update if the pub has been demolished since the last review said it was closed (usually just closed off on PG and no comment at all) - i do also add if a pub is still closed (and declining as a building) if not reviewed in a few years: this is especially true with regard to my Brum project as parts have never been, or not reviewed for ages.
MILD:
Debenham Suffolk had 4 open pubs in 1988
It now has 15 pubs listed on this site in 2014 with 2 open
I could go on and on listing towns villages and cities that have got hundreds of pubs that had closed down over 50 years ago,these seem to be mainly in the south.
I have some good old maps showing pubs in certain cities which have 30 odd pubs on a single road,all long closed some over 100 years ago,i wont mention which cities for fear of some photographers going there and adding yet more pictures of shops,banks and fast food takeaways and houses.
