Snake Island, BrazilEdson Campolina/Shutterstock
Brazil’s Ilha da Queimada Grande—dubbed Snake Island—is home to a dense population of one of the world’s deadliest snakes. The golden lancehead viper’s venom is so poisonous that it melts human flesh around the bite, and some claim there’s one snake per square meter in certain areas. For safety reasons, the Brazilian government doesn’t allow visitors, and a doctor is required on the team of any research visits.
U.N. buffer zone, CyprusKATIA CHRISTODOULOU/EPA/Shutterstock
Turkish troops invaded Cyprus in 1974, sparking a civil war between the Greek and Turkish inhabitants. When the fighting ended in a ceasefire, the United Nations took control of a no-man’s land “buffer zone” in the country’s capital, Nicosia. There, walls separate the Turkish community in the North (which Turkey, but no other countries, recognizes as a separate state) from the Greek community in the South. Behind the walls are abandoned homes and businesses. Some “Civil Use Areas” allow civilians, but other areas have been practically untouched for decades. Check out photos of the Nicosia airport and other eerie abandoned airports.
