Tucked away in these spooky woodlands, one man has amassed a huge collection of decaying trolley cars. Once a novel mode of public transport in the likes early 20th Century New York, the hauntingly beautiful trolleys are now at one with nature – a scene that abandoned location photographer Matthew Christopher was able to discover in a location not disclosed to the public. Here: Abandoned trolley graveyard in Pennsylvania. (Photo by Matthew Christopher/Abandoned America/Caters News Agency)

These images of abandoned hospitals across Italy are not for the faint-hearted. Both of the hospitals featured in the photographs are Italian asylums – known as manicomios – that were used as mental hospitals. Shut down by law in 1978, the derelict buildings are visibly overgrown and make for very eerie portraits. Photographer Thomas Windisch, 32, of Graz, Austria, said the asylums, located in top-secret spots, can get very creepy when there aren't many people there with him. Here: a hallway within an abandoned hospital. (Photo by Thomas Windisch/Caters News)

These pictures show the beautiful ruins of abandoned temples. The incredible shots, taken at temples in Angkor, Cambodia, show the striking yet haunting temples as they crumble to ruins. While they may have lost some of their former glory, the stunning temples show the beauty of the Cambodian landscape through the historic architecture. Here: Sun rises over the 5 towers of Angkor.

A spooky sight to behold! This is what a psychiatric hospital that has been abandoned for years looks like. Complete with bowling alley and a theater, the hospital shows just how much nature has weathered it over time as paint peels from the walls and the mattress gather dust. Here: This area of the hospital was last used as a day care center in the early 2000s. (Photo by Will Ellis/Caters News)

In the works of a photographer named Dave – who goes by Freaktography and never gives out his full name – haunting abandonment leaps from images of discarded machinery, tools and factory essentials. (Photo by Freaktography/Caters News Agency)

Six Flags New Orleans, also abbreviated to SFNO, is an abandoned theme park in New Orleans, Louisiana, that has been closed since just before Hurricane Katrina struck in August 2005 and is currently owned by the city of New Orleans. Six Flags had previously owned the park since March 2002, but after assessing the devastation caused by Hurricane Katrina and the related exorbitant expenses of repairing the damage, sought to terminate their 75-year lease with the city, beginning in July 2006 and finally succeeding in September 2009. The park is located in Eastern New Orleans, in the Ninth Ward of the city, off Interstate 10. Despite various announced plans to redevelop the site, as of 2014, it is still an abandoned amusement park in extremely poor condition. It is a well-known urban exploration destination.

A forest near Chatillion, a small village in Belgium, used to be home to a vintage car graveyard. This “car graveyard” has since been cleaned up, but photographer Theo van Vliet had the chance to explore the forest and photograph the cars beforehand. (Photo by Theo van Vliet)

The disused bobsled track from the Sarajevo 1984 Winter Olympics is seen on Mount Trebevic, near Sarajevo, September 19, 2013. Abandoned and left to crumble into oblivion, most of the 1984 Winter Olympic venues in Bosnia's capital Sarajevo have been reduced to rubble by neglect as much as the 1990s conflict that tore apart the former Yugoslavia.
