The Hidden Church is located in Cappadocia, Turkey, the most eye-catching area. Tourists come from all over the world to visit the Goreme Open Air Museum, a world heritage site that encompasses dozens of medieval cave churches. These churches transformed from natural caves are large and small, with individual internal structures, several connected and different sizes of caves, and some of the two or three layers of caves connected to each other, which is a perfect miracle. Many churches are decorated with murals of colorful religious scenes. The Dark Church, Brook Church or Tokal Church should be considered the best.
