What is catacombs maps?

Catacombs maps are maps of underground tunnels and passageways, usually used as burial grounds for the dead. These tunnels were commonly used by early Christians, Jews, and Romans to bury their dead and were often adorned with artwork and symbols. Catacombs maps are typically hand-drawn and show the various rooms and passages within the catacombs. They can also indicate the location of important graves, chapels, and other significant features. Many of these maps are centuries old and provide insights into the past cultures and religions that used them. Today, many of these catacombs are popular tourist destinations and are open for visitors to explore.
