In the spring of 1814, as Denmark-Norway crumbled under Napoleonic fallout, 112 delegates converged on Eidsvoll Manor House in Eidsvoll Verk
Eidsvoll 1814 – The Clandestine Oath
You are a young archivist at Eidsvoll Manor, in April 1814, tasked with securing the Constituent Assembly's most precious documents.
From April 10 to
Immerse yourself in 1814 Eidsvoll, the cradle of Norwegian democracy, and thwart a conspiracy threatening the birth of a nation.
The story that haunts this land
Your adventure begins on the forecourt of Eidsvollsbygningen, at 17 Carsten Ankers veg, Eidsvoll Verk. This major Norwegian national monument was the scene of the Constituent Assembly which, from April 10 to May 20, 1814, brought together 112 delegates to draft and adopt the Norwegian Constitution. The manor, now the Eidsvoll 1814 Museum, is the cradle of Norwegian democracy. Your first clues are etched into the stone of the Wergeland House, the Democracy Centre, inviting you to decipher the beginnings of the conspiracy.
Continuing your investigation within the Eidsvollsbygningen park, you walk along the Vorma river, a major waterway in Innlandet that was a central geographical element of the political landscape in 1814. The banks of the Vorma, once strategic navigation routes in Eastern Norway, whisper the echoes of the debates that stirred the delegates. Augmented reality figures of Carsten Anker, the businessman and owner of the manor, reveal anecdotes about the economic tensions of the era.
The route then leads you to Eidsvoll Verk, a former industrial site transformed into a museum, testifying to the rich economic past of the Eidsvoll region. Here, at Stallgården, among collections of historic sleighs and carriages, the chamberlain's automobile, a prestige vehicle, might conceal a crucial message. This site, located in the immediate vicinity of the manor, is integrated into the regional tourist route and offers you a glimpse into the infrastructures that supported the events of 1814.
Your quest then takes you to Eidsvoll Kirke, the historic church of Eidsvoll. This major religious edifice, present in the urban and spiritual context of 1814, saw many of the actors of the Norwegian Constitution pass through its doors. Its historic built heritage contains symbols that, once deciphered, can confirm the existence of the clandestine oath. The church walls, anchored in the Eidsvoll Verk sector, are silent witnesses to the hopes and fears of the young nation.
Returning towards Eidsvollsbygningen, the Eidsvoll 1814 Museum, you gather the last pieces of the puzzle. This Innlandet heritage site, preserved by the Norwegian Museums of Cultural History Foundation, is more than a historical museum: it is a living symbol of Norwegian national cultural heritage. By completing your Eidsvoll escape game, you will have not only unmasked the plot but also explored the cradle of Norwegian democracy, discovering the history of the 1814 Norwegian Constitution and the vision of figures like Henrik Wergeland, a 19th-century Norwegian poet and democracy figure.
