What are rock churches?

Rock churches are churches that are built directly into natural rock formations or caves. These churches are typically carved out of solid rock and may feature intricate carvings, frescoes, and other decorations. Rock churches are often found in regions with soft rock formations that are easily carved, such as in Ethiopia, Turkey, and India. These churches are often considered to be architectural marvels and are important religious and cultural sites for the communities in which they are located.
