Johnny Joo (pronounced 'yo') is a 24-year-old photographer and urban explorer from Ohio. He began to explore abandoned structures when he was 16, becoming fascinated that these spaces belonged to someone's past.

"People were here once, living and working and now they are gone, while the collapsing ruins remain," he says. "It opened my eyes to a whole normally unseen part of life and the world around me. It captured me in such an incredible way, and I now attempt to capture it just as well as it has me."

Here at IBTimes UK we are big fans of his work, having previously published his haunting photos of an abandoned mall. Joo has kindly sent us a selection of the photos he took in 2014.

Hillandale Park in Euclid, Ohio. Still a regular park, though not in the best neighbourhood, this was a failed attempt to create a type of closely-knit community organisation throughout this park. With the crime rates rising, the project was left and never touched again. Holes now cover the top of the bridge, so don't go walking at night or you might fall through... or offwww.facebook.com/JohnnyJooPhotography

Looking directly up inside the former Warner & Swasey space observatory in Cleveland, Ohio. Around the 1970s, light pollution had grown far too bad to continue seeing the night sky from this locationwww.facebook.com/JohnnyJooPhotography

A curiously hidden temple in Cleveland's East side. This temple has sat for many years, rotting away. I feel that it may not have much longer, but is one of the few remaining in this architectural form herewww.facebook.com/JohnnyJooPhotography

A countryside school abandoned since the 1960s. With such a low local population, and only a few classrooms, any students here were bused into larger schools with children from surrounding areas. The walls have been rotting away, some to the point where they have completely fallen downwww.facebook.com/JohnnyJooPhotography

Inside a forgotten countryside home, an entire wardrobe has fallen to the ground, sinking through the soaked wood, getting heavier each time it rains. I am sure very soon it will come down completely. The clothing created an almost egg-sac appearance hanging into the kitchen belowwww.facebook.com/JohnnyJooPhotography
