Fredrikstad, an hour south of Oslo by direct train, holds Gamlebyen, Northern Europe's best-preserved fortified old town, its star-shaped ramparts and surrounding moat dating from the 17th century and still substantially intact today. The journey out is short enough, and the old town flat and compact enough, to make this a genuinely easy day for legs still recovering from a marathon, without the longer travel commitment of Bergen or the more active climb required at Drøbak's Oscarsborg.

Trains run hourly from Oslo S, modern and comfortable, at a cost of around 215 kroner for the journey.

Crossing to Gamlebyen

From Fredrikstad's modern town centre, most visitors cross the Glomma river to Gamlebyen on a free local ferry, a short, flat crossing that sets up the old town's fortified character well before arrival. Fredrikstad sits at the mouth of Norway's longest river, and the old town's position on the water was central to its original defensive purpose.

The Ramparts and the Old Streets

Inside the walls, Gamlebyen's cobbled streets are lined with well-preserved 17th- and 18th-century buildings, many now housing small shops, galleries and cafés rather than their original military or merchant functions. The star-shaped ramparts themselves can be walked in a loop, flat underfoot for most of the circuit, with views back across the moat and river; this is a level, unhurried walk suited to a day after the marathon rather than a demanding hike.

Where to Eat

The streets inside Gamlebyen carry a scattering of cafés and restaurants set into the old fortress buildings themselves, an atmospheric setting for a relaxed lunch without needing a specific recommendation given how contained and walkable the old town is.

Getting Back

Return by the same direct hourly train service to Oslo S. Check the current timetable before leaving the old town, since afternoon departures can fill during busier periods.
