Isegran fort, Naval fortification on Isegran island, Fredrikstad, Norway.
The fort stands at the confluence of Østerelva and Vesterelva rivers, featuring defensive walls and a tower on an 80-acre island in Fredrikstad.
Earl Alv Erlingsson constructed the initial wooden fortress in the 13th century, which was later destroyed and rebuilt with stone fortifications in the 1670s.
The fort maintains Norway's sole boatbuilding school and a maritime center dedicated to the construction and restoration of traditional wooden vessels.
Visitors can access the fort via the Kråkerøy Bridge or by taking the free City Ferry service that operates in the area.
The Empirehuset, Fredrikstad's oldest wooden structure dating over 300 years, remains preserved within the fort's grounds.
