In 1814, Norway broke away from the union with Denmark and wrote and signed its own constitution. However, Norway was brought into a union with Sweden.
King Christian Fredrik stayed at Konventionsgaarden for many weeks during the negotiations with the Swedish crown prince Karl Johan. On the 14th August, “the Konvention at Moss” was signed. It saved the Norwegian constitution and the parliament house.
Konventionsgaarden is only available to the public on announced viewings or by group appointments.
