The village often changed its location in the past, because of the persistent raids by the Caucasian Laz pirates. The contemporary Rezovo was inhabited in 1903, and soon the new Ss. Constantine and Helena Church was built. This is evident from the “All Saints” icon, by the late icon-painter G. Poliksoidu, and dated back to 1909.
