The Last Days of Dolwyn
Now having had a good peruse of your excellent site, I though you might like these two photos.
They are of the location for the images you have for the film The Last Days Of Dolwyn.
This is a film I have not seen - but I would love to know where it can be obtained.
I note from the IMDB that it is about a Welsh valley that was flooded in order to supply water for Liverpool.
The location of the two photos you have on your site is in fact Lake Vyrnwy in what was Montgomeryshire, Mid Wales.
It would appear the the subject matter of the film is based in part on fact - viz the extract below form Wikipaedia:
From Wikipedia, the free encyclopedia
Lake Vyrnwy Nature Reserve and Estate (Welsh: Llyn Efyrnwy) ([pronounced [E]VURN-WEE]) is an area of land in Powys, Wales, surrounding the Victorian reservoir of Lake Vyrnwy. Its stone-built dam, built in the 1880s, is the first of its kind in the world. The Nature Reserve and the area around it are jointly managed by the Royal Society for the Protection of Birds, and Severn Trent Water. It was built for the purpose of supplying Liverpool and Merseyside with fresh water. It flooded the head of the Vyrnwy Valley and submerged the small village of Llanwddyn.
My family came from this area, and I happen to have the attached photos that I took myself in 2007 which almost reflect the same angles.
