In 1660, Duke Jacob of Courland purchased Eidsvold Iron Works from the Danish King and had 120 artisans relocated. The iron works was its best era of operation under Heinrich von Schlanbusch (1688-1705) who received the property as the gift of King Christian V and his son Georg Theodor (1705-1750).

Eidsvoll Manor (Eidsvollsbygningen) is a historic Manor House. The building was first constructed ca. 1770. As it stands today, the manor is the result of an extensive renovation and modernization in the years around 1800 by Carsten Anker. He took residence in Eidsvoll in 1811, rebuilding the house which is now the Eidsvoll Manor. When the building was finished, it was one of the largest and most modern private residences in the country. Inspiration had been received from the then-modern Danish and French architecture. The building bears stylistic stamp of classical architecture. The total floor area of the building is over 2,000 square meters.

In 1814, the Constitution of Norway was signed at Eidsvoll on May 17, now known as Norwegian Constitution Day. Carsten Anker went bankrupt in 1822 and the estate was sold at auction in 1823. A group of private citizens by Henrik Wergeland organized a fundraiser that allowed them to buy the building with the pavilion and the garden. In 1851 the Parliament of Norway took over Eidsvoll Manor. Eventually the property was preserved and operated as a public museum.
