Hakoinen Castle, Medieval hillfort in Janakkala, Finland.
The remains of Hakoinen Castle stand on a steep rock formation that rises 63 meters above Lake Kernaala in southern Finland.
Built during the late 13th century, this fortification served as a Swedish stronghold and endured a three-day siege by Novgorodian forces in 1311.
The archaeological excavations of the castle revealed a dual construction method, with wooden structures at the bottom and brick buildings at the top.
The site requires a moderate climb up the hill, and visitors can complete their exploration of the castle ruins within 45 minutes.
The fortress contained both lower defensive wooden structures and upper brick constructions, including a single tower overlooking the surrounding landscape.
