25. Nicosia International Airport, Cyprus
Nicosia International Airport was a busy, successful airport from the time it opened in the 1930 until it was abandoned in 1974, due to—you guessed it—the Turkish invasion of Cyprus. In the past 40+ years, planes have turned to rust outside, while the airport’s check-in counters and boarding areas have accumulated thick layers of dust and bird droppings.
26. Anping Tree House, Tainan City, Taiwan
Originally a British-owned merchant warehouse, this crumbling complex in Taiwan has been overtaken by nature—much to our visual delight. After the warehouse was vacated sometime in the 19th century, a nearby banyan tree forced its way through the building’s brick walls and concrete floors, creating a “treehouse” that looks like one of Angkor Wat’s baby cousins. Today, visitors can explore the whimsical site for a few dollars—there’s even an elevated walkway to help you navigate.
