"Never mind oak panels or a lovely medieval arch, it's blast doors and a decontamination chamber for you out at York's Cold War bunker. Designed as a nerve centre to monitor fallout in the event of a nuclear attack, the bunker actually remained in service until the 1990s. Times have thawed but you can still immerse yourself in a subterranean world and imagine what could have been, surrounded by some colourful mid-century interiors." - Abell Design
