Photographer Cristobal Palma has sent us this recent set of images taken at the unfinished International Fair of Tripoli, Lebanon, by Brazilian architect Oscar Niemeyer.
Construction stopped in 1975 at the outbreak of the Lebanese civil war and was never restarted.
The 10,000 hectare site comprises 15 buildings by Niemeyer and was added to the World Monuments Fund's list of 100 most endangered sites in 2006, in response to plans to turn the site into a theme park.
Despite being deserted, the site is a popular attractions for tourists interested in architecture.
Tripoli is the second-largest city in Lebanon and is located 50 miles north of Beirut.
