Transylvania - After the first Ottoman attacks on Transylvania in the first half of the 15th century, the defence of the country was organized. If there was no castle or fortress nearby, walls were built around churches offering some protection to the surrounding villagers. These makeshift fortresses are referred to as fortified churches. This picture above shows the church of Kézdiszentlélek, which was fortified with walls and circular bastions, in 1401, by Kata Apor, a local heroine. The original church was gothic, but was modified to baroque style in the 18th century.
