Temporarily closed

Website Directions

Temporarily closed (expected until 2028). The castle is closed to visitors because of the Slotsprojektet (new visitor building, new ring wall, raising of the watchtower; construction from 2026); reopening is planned for 2028. Until then, the neighboring Borgmestergården (Slotsgade 11) shows an exhibition about the project, and from April to October there are free outdoor castle walks on Saturdays.

About the museum

The castle is first mentioned in 1193 and, according to archaeological findings, was complete with moats around 1209/10 – as a ring-wall castle for King Valdemar Sejr. The core of the surviving palace building dates from the early 13th century, and the great watchtower was built around 1300. Because of its central location on the water, King Erik Klipping used the castle as a meeting place with the magnates of the realm; in 1282 he signed Denmark's first constitution here, and in 1287 the suspected murderers of the king were outlawed at a Danehof. Until 1413 the medieval parliament, the Danehof, met regularly at the castle.

After Nyborg became the country's first residence town in 1525, the castle was extensively rebuilt and, under Christian III in the 1550s, reinforced against artillery; a rampart system arose around the town and castle. In the Swedish wars of the 1650s the castle was occupied and plundered; afterward the military used it as an arsenal and granary until 1913. Large parts of the complex were demolished during this time.

In 1916/17 the Nationalmuseet took over the castle and had it restored by the architect Mogens Clemmensen, after which it was opened to visitors. Today Østfyns Museer operates the museum. As part of the Slotsprojektet, the King's Wing was restored in 2018–2022 and the market square redesigned; since 2026 a new visitor building, a new ring wall and a raised watchtower have been under construction. For the planned reopening in 2028, the exhibition "Kongen Kommer" is to tell 400 years of Danish history.
