Rød Herregård was built in the 1730s for a family that made its fortune in the timber trade that once defined Halden's economy — ships loaded with Norwegian timber left this fjord for markets across Europe. The manor stayed in the same family for generations and is furnished largely with their own possessions, giving it an unusually intact, lived-in feel rather than the reconstructed look of many historic houses.
The surrounding park and outbuildings, including an old distillery, are part of the visit. It's a quieter counterpoint to the fortress on the hill — a look at the merchant wealth that Halden's strategic position also made possible.
