Cave churches are places of worship carved into rock formations, often found in regions with volcanic or soft stone. These structures date back to early Christianity, when believers sought refuge from persecution. They can be found in various locations, including Turkey and Ethiopia, showcasing unique architectural styles and religious art. Many cave churches feature intricate frescoes and altars, reflecting the spiritual significance of these sites. Some, like the Göreme Open-Air Museum in Cappadocia, are UNESCO World Heritage Sites, attracting visitors interested in history and religion. These churches serve as a testament to the resourcefulness and faith of early Christians.
