16. Underwater City in Shicheng, China
This incredible underwater city, trapped in time, is 1341 years old. Shicheng, or Lion City, is located in the Zhejiang province in eastern China. It was submerged in 1959 during the construction of the Xin’an River Hydropower Station. The water protects the city from wind and rain erosion, so it has remained sealed underwater in relatively good condition.
17. The Abandoned City Hall Subway Stop in New York, U.S.A.
John Paul Palescandolo & Eric Kazmirek
This beautifully-designed metro station sits underneath City Hall in New York City. Because of its location, much attention was given to its design, but nearby stations ensured that this one never received a significant amount of traffic, and its curved layout made it unsafe for use with newer, longer trains. The station was closed in 1945 and, because of security concerns, it generally remains closed, with the exception of occasional exclusive tours.
