Have you ever visitied Burlington? Didn’t think so. It’s an underground ‘city’ underneath the town of Corsham. The BBC Wiltshire website has a series of videos and panoramas that show off this ex-Cold War complex.
The place is huge, containing over 60 miles of roads. It could sustain 4,000 people for up to 3 months in complete isolation.
