The artist mentioned above is the international street artist JPS, whose real name is Jamie Paul Scanlon. He is known for various projects worldwide—for example, turning an abandoned mental hospital in the UK into a destination for art lovers—and his followers know he's drawn to abandoned places. With his unique painting style using stencils and freehand, the self-taught British artist manages to bring his artworks to life.

Even though the range of his works is widespread, everyone who's followed his art over the years knows he's a fan of classic horror and movie characters—and this love shows in the hidden gallery which was named Graff Endorsed.

In just a few weeks, he created an exhibition that can be described as a dream or a nightmare. Some visitors may not even dare to enter the place after being greeted near the main entrance by a hoard of bloody zombies lurking through a broken window at the main entrance. Others may be brave enough to stumble over an almost 2-meter-high xenomorph from Ridley Scott's "Alien" or to find the little evil grinning gremlin with a can of spray paint.

And if blood and horror movies aren't scary enough—then maybe the shark which can be spotted through a hole or the massive spider casting a shadow on the wall gives the visitors goosebumps.

So far, you can discover over 30 artworks by JPS in all sizes at Graff Endorsed—and the numbers are rising continuously.

Different from the hyperrealistic artworks are the installations by a young artist called Rage. These installations—built solely from material found on site—are either just breathtaking or thought-provoking.

From Cell 5 (a detailed reconstruction of a police cell in which a refugee burnt to death in 2005 under mysterious circumstances) to various card houses made with doors of the abandoned building, his artworks are surely special and unique.

Long story short: Graff Endorsed is a fascinating and unique permanent and growing art exhibition by JPS and Rage and definitely worth a visit—if you know someone who knows where to find it.
