Beautiful 400-year-old artwork hidden within underground chapel left abandoned for nearly four decades

This underground chapel left abandoned for nearly four decades holds beautiful 400-year-old artwork hidden within.

Used as a hideout during the second world war, this former marl quarry hosts spectacular drawings of religious figures believed to have been sketched from chalk.

The sprawling scenes depict biblical moments of Jesus, angels and other important Christian figures alongside other murals.

The chapel at the deepest depths of the quarry, where most of the pieces can be found, is untarnished by tags or graffiti like others in the area.

After serving as a safe-zone during the war, tours were given in the 1970s until the quarry was deemed instable and closed.

Urban explorer Bob Thissen, from Heerlen, the Netherlands, believes the beautiful pieces should be preserved in a museum before nature has time to destroy them.

He said: “The best part about this quarry are the up to 400-year-old drawings.

“You see a lot of religious figures like Jesus, angels and similar paintings which you expect to see in a regular church.

“The drawings are gorgeous and very detailed, they should be kept in a museum to be preserved. It’s only a matter of time until nature destroys them.

“I did not want to touch the drawings to check what they were made of. My guess would be chalk or it would be made black by fire and then carved.

“There are tons of quarries in the south of the Netherlands, but most of them are pretty big and full of tags and graffiti.”

Bob had visited the location multiple times before but finally decided to document the location’s awing artwork after fearing it would deteriorate beyond repair.

He filmed it for his YouTube series Exploring the Unbeaten Path, which captures abandoned building all over the world.

Bob said: “Most of the paintings are made inside the chapel, which you often see in the quarries in this area but this one is perhaps the best I’ve seen.

“They hid and lived in this marl quarry during WWII, so the chapel has been visited often. The chapel was made in the deepest point in the quarry.

“I have been here multiple times during the years, the last time was in 2018. It’s a gem in the area where I live.

“It’s a good place to clear your head. It’s unbelievable quiet and calm in there. The temperature is always 11 degrees, so you can warm up in the winter or cool down in summer.”
