My friends took me to a small wooden Church literally in the middle of a forest - accessible by only dirt roads. They explained to me that the Ottoman Turks (who subjugated much of the Balkans for over 500 years) forbade Serbs to worship. The Serbs in this region then constructed this hidden Orthodox Church (along with thousands of other Churches and Monasteries throughout Serbia) without the knowledge of the Ottoman authorities, worshipping in secret.
