The most beautiful military monuments Fredrikstad

The Fredrikstad fortress is the only one in the country still standing with ramparts. Built between 1663 and 1666 by Willem Coucheron and his son Anthony Coucheron on the orders of the Danish-Norwegian King Frederik II, it is modelled on Dutch fortresses and features a wide moat which, curiously, forms a half-star shape around the old town. It was only attacked once, in 1814, during the war between Sweden and Norway.
