Architecture firms Cubo and jaja, along with a team consisting of VMB, Schul, Søren Jensen and Mogens Morgen, have been named winners of a competition to revitalise a 15th century castle on the Danish island of Funen.

The medieval Nyborg Castle – the site where Denmark’s first constitution was signed in 1282 – will feature a new exhibition wing and visitor centre, as well as bridges for visitors to approach the castle on its original axis and heading towards an existing library. The castle will also undergo a restoration, with the royal wing and historic watchtower to undergo works. The royal wing, which will also become the new entry point for the castle, will be made wheelchair accessible throughout, with central heating also to be installed.

The architecture collective was selected from six international teams, invited in May last year to submit entries for the competition. Those six were then narrowed down to three in October.

The jury stated that the winning design was “a convincing and site specific architectural statement and atmosphere that emphasises the history of the castle and its new function as a museum.”

The budget for the project has been set at DKR280m (US$42.7m, €37.6m, £29.2m). In a statement from jaja, the architect said the plans would “revitalise the medieval capital of Denmark” when the project is completed in late 2019.
