Medieval stronghold, Mielno.

A Slavic settlement located there in the 9th century was reconstructed on the outskirts of the Koszalin Seaside Park. An earthen cone surrounded by a moat was built in the very center. More than 100-year-old beeches and oaks give this place additional charm. The Society of Living Archeology several times a year – mainly during the holiday season – organizes melee combat shows, craft workshops, and tastings of food and drinks consumed at the time of the existence of the castle.
