The ghost town in Wales that is cut off from the rest of the world

Stuck on a hill 1,100ft above sea level, surrounded by the breathtaking scenery of the Rhondda Valley, Penrhys has never been able to shake off the bleak reputation it's had since it was first built in the late 1960s. With boarded-up houses, overflowing litter attracting rats, and piles of burnt-out fires, this notorious estate seems well worthy of the title of 'the most depressing place to live in the UK'.
