The Chapel of Saint John the Theologian is located in Skala, close to the port’s waterfront; next to it there are the preserved ruins of building, which during the Early Christian period was used as a «baptistry». According to tradition, this is where Saint John the Theologian baptized the Patmians, while another tradition mentions that this is where the Saint stood when he banished the magician Kynops (or Kenepsi) to the bottom of the sea. The Chapel of Saint John is joined to a smaller chapel dedicated to Saint Polycarpos.
