Isegran fort

Isegran fort is a fortification on an island where two rivers meet in the Fredrikstad area, marked by defensive walls and a tower. The entire complex spreads across the island grounds, where military structures stand alongside a boatbuilding center.

The original wooden fortress was built in the 13th century, then destroyed and rebuilt with stone fortifications in the 1670s. This transformation made it a major military stronghold for the region.

The fort is home to Norway's only boatbuilding school, where traditional wooden vessels are constructed and restored by hand. This craft remains central to how the place is experienced and used today by both craftspeople and visitors.

Visitors can reach the fort using the Kråkerøy Bridge or a free ferry service that operates in the area. The best time to explore is during daylight when the walls and structures are easy to see.

The Empirehuset, a wooden building more than 300 years old, stands on the fort grounds and is Fredrikstad's oldest structure of its kind. This house shows how people built with wood in an earlier era and offers a glimpse of construction methods from the past.
