LOC2323: Labyrinth of tunnels dug into chalk (Bromley, London)

It's dark, it's a labyrinth, it will make a great chase scene. The caves go on for miles and miles and are totally unique. They can look like stone even though they're chalk. If you want control Mondays and Tuesdays are free from other visitors. Should mention that being a cave, there is echoey sound. (Bromley, London)
