Rapola Hill Fort, located in Sääksmäki within Valkeakoski, Finland, is the largest hill fort discovered in the country, encompassing approximately 58,000 square meters. Constructed primarily on a natural ridge rising 65–70 meters above Lake Vanajavesi, the fort features remnants of earth walls and was likely fortified with wooden structures atop the ramparts. Archaeological evidence suggests its origins date back to the Viking Age (800–1000 AD), with habitation traces reaching as far as the 7th century.

Historical records mention a "King of Rapala" in 1340, linking the site to regional power dynamics. The fort's strategic position provided visibility to other fortifications up to 30 kilometers away, underscoring its significance in controlling the Vanajavesi water route.
