Eidsvoll is a municipality in Akershus county, Norway. It is part of the Romerike traditional region. The administrative centre of the municipality is the village of Sundet. The first element is the genitive case of the word eid (Old Norse: eiđ) and the last element is voll (Old Norse: vǫllr) which means "meadow" or "field". The meaning of the word eid in this case is "a road passing around a waterfall". People from the districts around the lake (Mjøsa) who were sailing down the river Vorma, and people from Romerike sailing up the same river, both had to enter this area by passing the Sundfossen waterfall. Because of this, the site became an important meeting place long before the introduction of Christianity.
