“St. Iliya” chapel situates 2 km south-west of Devin in Ravnya area. It was built in the 1930s, and up to the 1950s it was permanently open and annually, around the day commemorating St. Ilya (2nd of August), attracted thousands of people from the town and the region. At the time of building the chapel and during later excavations (1970) traces of funerals, parts of potter iron tool, wall remains and others were found.
The artifacts found gave the archeologists ground to claim that the chapel was built over and old cult place (a church or a monastery with small necropolis). This is supported by the existence of a big and permanent water source.
