From a derelict mansion hiding in a farmer's field to a row of workers' cottages crumbling into nothing, some significant historic and cultural building in Wales are in danger of being lost forever, a new TV programme warns.
In his latest show, BBC Wales presenter Will Millard explores the crumbling ruins of some of the country's great architecture to tell the stories behind these remarkable places.
He visits Gwylfa Hiraethog in Denbighshire, said to have been built in the 1890s which was once an Edwardian hunting lodge so fancy that only the very elite of the country were invited and allowed to visit.
