In the stream of Palia Kavala were operating in the past 13 water mills, and three water fountains. Today, unfortunately, very few of them survive, most of them are ruined, destroyed and covered with dense vegetation. The last mill of the village worked until the early 1970s.
The existence of these watermills is an integral part of the way of life of the villagers in the recent past and part of their economic activity. Through their ruins, important elements of the tradition and history of Palia Kavala are revealed. It is characteristic that these watermills supplied flour to the wider area of Kavala even during the period of the Bulgarian occupation, when the local millers, at the risk of their lives, worked secretly at night to produce some flour.
The Cultural Association of Palia Kavala could not remain indifferent to the abandonment and neglect of these watermills. On the initiative of its members, the restoration and maintenance of one of them began in 2008. Part of the old equipment was saved and maintained, and new equipment was installed where needed, such as millstones, barrels and other accessories.
