Having been founded in the year 315 BC, the town has many fine churches, some of which were built according to the plans of three-nave basilicas, while others were based on the architectural plans that portray a Greek cross. Built between the 4th and the 15th centuries, these churches were pretty influential in the Byzantine world.
