The World’s Most Claustrophobic Places:Underground Ancient City - Turkey

A large city capable of holding up to 20,000 people may not sound like the most claustrophobic of places, but when you consider the ancient city of Derinkuyu in Turkey is located 60 metres underground, you might start to understand why it made this list. The 5,000-year-old city is built over a number of levels and has narrow passageways and tunnels connecting each section. Definitely not a place to live if you suffer from claustrophobia!
