Örön linnake

Örön linnake is a coastal fort on an island in Kimitoön, Finland, located within the Archipelago Sea National Park. The site holds military structures including barracks, artillery pieces, defensive positions, and fortification walls distributed across the landscape.

Construction of this fort began in 1915 as part of the Russian Empire's Peter the Great Maritime Fortress defensive system. The site served as an active military installation with multiple artillery batteries throughout the 20th century.

The Finnish Heritage Agency recognizes this fort among 1200 nationally significant heritage sites, preserving Finland's architectural and military history.

Reaching the island requires boat access from a guest harbor. Marked hiking trails ranging from 6 to 11 kilometers offer ways to explore the different areas and structures on site.

Over a century of military use unintentionally created a refuge for rare wildlife, making this site one of southern Finland's most important locations for endangered species. The combination of military heritage and nature conservation creates an unexpected character to the place.
