Disturbing photos show the creepy chapel decorated with the bones of over 40,000 HUMAN SKELETONS

TAKE a look around the chilling interior of an ancient underground chapel decorated with the remains of thousands of people.

The holy building, located in the Czech Republic, is known as the "Bone Church" and comes complete with a chilling backstory to accompany its creepy image.

The Czech chapel, officially called the Sedlec Ossuary, is built under the grounds of a former cemetery, and makes use of the graveyard's deceased residents to decorate its elaborate interior.

After being founded in the 1200s, the cemetery quickly filled up, and had become the final resting place of over 30,000 people by the 1400s.

Plague victims and fallen soldiers were numbered among the thousands of dead in the Sedlec Cemetery, which was completely full by the end of the 1400s.

With no more room to bury anyone else, all the remains were eventually dug up and moved to the underground chapel, where piles of bones were stacked up in sinister pyramids.

Until 1870, the heaps of human remains stood piled up in the chapel, before a noble family hired an artist called František Rint to turn the bones into deathly decorations.

Now the remains of over 40,000 people adorn the chapel walls, with the bones of as many as 70,000 deceased Czechs decorating the creepy building, which sits underground the Cemetery Church of All Saints in the picturesque town of Sedlec.

Masterfully-arranged bleached bones cover almost every ornate surface, whilst a chilling chandelier made out of human bones hangs from the chapel's ceiling.

This grand fixture is allegedly made from one copy of every bone in the human body, and forms the creepy centrepiece of the cavernous building.

Other bony fittings include a morbid goblet made from human remains, whilst a huge mound of remains lies piled up in one of the building's dingy corners.

This is certainly a place you really would not want to spend the night in.
