Kamen Bryag (Yailata), Bulgaria; September 5, 2020; Yailata National Nature and Archaeological Reserve is located 1.5 km southern from the village. Although Yailata is a bit far from the most popular resorts and hence is little known as a tourist attraction, it is one of the most amazing places along the Bulgarian coast. The big cliffs make this area almost unaccessible, except via a few narrow paths among the rocks. The fields there end abruptly with high rocks descending straight to the sea level. About 40 caves can be found in the vertical cliffs hanging over the sea.

A monolithic church or rock-hewn church is a church made from a single block of stone. Because freestanding rocks of sufficient size are rare, such edifices are usually hewn into the ground or into the side of a hill or mountain. They can be of comparable architectural complexity to constructed buildings. About 40 caves can be found in the vertical cliffs hanging over the sea.
