Hospital (formerly the South Wales Sanitorium). Following closure, the buildings and surrounding estate were sold to the former Chief Medical Officer for just £227,000. Plans were subsequently made to redevelop the site as business park, and indeed several buildings were converted and occupied by local companies as part of the Black Mountains Business Park. However, due to the site's isolated location and the global recession, the venture failed and only one or two businesses remained on the site by early 2009. In 2009 the site was offered for sale. By this time, several properties that once belonged to the hospital, such as the gatehouse, had been sold off and the buildings were becoming derelict. It featured in Season 1 of the BBC series Hidden Wales where its plight was brought to attention. There are signs of demolition throughout the site and many of the original slates (believed to be worth in excess of £1 million) were stripped from the roofs. The large derelict site has become an attraction to many urban explorers despite improved security measures.
