High Quality Content by WIKIPEDIA articles! The Church of St John the Baptist (Bulgarian: църква „Свети Йоан Кръстител“, tsarkva „Sveti Yoan Krastitel“), also known as the Church of St John the Precursor or, locally, Sveti Yani or Sveti Yan, is a small medieval Eastern Orthodox church in the town of Asenovgrad in Plovdiv Province, south central Bulgaria. The church is located on a cliff west of the town and dates to the 12th–14th centuries. Its exterior is decorated with many blind arches, while its interior features mostly frescoes from the 18th century, with some fragments of 14th-century murals. Its high position and the arrowslits on the north wall made the church suitable as a defensive outpost.
