Munkholmen

63.4510° N, 10.3835° Ehistoryarchitecturebeachnature

A tiny wooded islet in the Trondheimsfjord, ringed by a round 17th-century fortress and layered with a thousand years of monks, prisoners and executions.

Munkholmen — "the Monks' Islet" — is a small islet in the fjord just off Trondheim, and few places pack in so much history. In pagan times it was the city's execution ground; around 1100 monks founded Nidarholm Abbey here, one of Norway's oldest monasteries. After the Reformation its stone was reused for a round fortress begun in 1658, which became a state prison and coastal battery, and in the Second World War a German anti-aircraft position. Today the uninhabited islet, barely 13,000 m², is Trondheim's favourite summer excursion, with a small beach and a café.

Munkholmen Fortress

The round, thick-walled stone fort begun in 1658 after a Swedish siege of Trondheim, later a state prison and coastal battery — it still crowns the whole islet.

Nidarholm Abbey

One of Norway's oldest Benedictine monasteries, founded on the islet around 1100 — it gave Munkholmen its name ("the Monks' Islet") and its ruins were quarried for the later fort.

The gallows islet

Long before the monks, the islet was Trondheim's execution ground; in 995 the severed heads of the defeated Earl Haakon and his slave Kark were displayed here on stakes facing the fjord.

The beach and café

A small sheltered swimming beach and summer café below the fortress walls make the islet Trondheim's favourite warm-weather escape.

Tradition

The boat from Ravnkloa

In summer a small passenger boat shuttles across from Ravnkloa in the city centre, a short hop that has made the islet a classic Trondheim day trip.

Best time to visit
Late May to August, when the boat from Ravnkloa runs, the café and beach are open, and the northern days stretch almost endlessly — around midsummer the sky barely darkens. Outside the summer season the islet is closed and there is no ferry.
