The rock complex, dating back to the 6th century, has been named among “gems of Europe’s cultural heritage” by Europa Nostra, a major continent-wide heritage organisation.
Unveiled on Thursday, the list includes such European sites as several Post-Byzantine Churches in south-eastern Albania and the Buzludzha Monument that served as the Soviet-era headquarters of the Communist Party of Bulgaria.
