Oulu Castle, Medieval fortification in Oulu, Finland
The remaining structures of Oulu Castle include a chancellery cellar and rampart section on Linnansaari island in the Oulu River delta.
Swedish forces constructed Oulu Castle in 1590 as a strategic stronghold against Russian advances, using wood and earth for the initial fortification.
The castle site maintains an exhibition space in the cellar, presenting the evolution of Oulu from its early settlement through various historical periods.
Visitors can explore the castle grounds and cellar during the operating hours of Tähtitorni Café, which occupies the 1875 observatory tower.
A lightning strike in 1793 caused an explosion in the gunpowder magazine, leading to the final destruction of the original castle structure.
