Beneath Paris lies the mysterious Catacombs, a silent labyrinth housing the remains of over six million people. Originating from a public health crisis in the late 18th century, these repurposed limestone quarries became the solution to the city's overflowing cemeteries. Bones were ceremonially transferred and arranged along the catacombs' walls, drawing fascination and curiosity over time. Now a popular tourist attraction, they offer a unique glimpse into Paris's past, extending across a vast network beneath the bustling streets.
