Buildings Where the Walls are Lined with Human BonesS

Looking for a setting for your next haunted horror movie? Many of the ornate and elaborate ossuaries around the world serve as grim reminders of mortality, and evoke an eerie sense that their skeletal walls could suddenly spring to life.

While many of these ossuaries are attached to churches, the reason they were constructed is often practical: where there wasn't enough space for a graveyard (or when an existing graveyard was needed for other purposes), the cleaned bones were instead interred inside buildings and catacombs. However, others were created as a reminder of our mortality, and one listed below (The Skull Tower, located in Niš, Serbia), was deliberately meant to evoke horror from the enemies of the Ottoman Empire. More about these and other ossuaries is available at Atlas Obscura.

Fifty-eight currently remain:
