The Margravina and I took an afternoon perambulation. Direct from the house, owing to the wines imbibed over a very nice lunch with my eldest sister and brother-in-law. Walking up Coombe Lane West, in the Coombe area of Kingston, we noticed the gate to Coombe Conduit was open. I mentioned this English Heritage property a couple of years ago on a walking blogpost. It is rarely open. So we popped in for the first time in two decades.
Here are a few snaps. Apologies for the misalignment of the first one. I only noticed when it was too late to do anything about. It should give you an idea though.
The site was staffed by members of the Kingston Society (a local conservation pressure group - I came away with good intentions of looking into this further). One of them explained that the ruined building was damaged indirectly by a bomb in the War. A tree was blown down by the explosion and it fell on the building, and wrecked it.
