Vinger Royal Road (Eskoleia) was the historical name of an ancient route in southern Norway.
In Koppom in Eda Municipality, there was an old chapel site from pilgrimage hikes to Nidaros, with cross and altar called Eskoleia Uligama.
From Sweden, Eskoleia went from Vingulmark (the land south and east of the Oslo Fjord) over Raumariki along Glomma further over Sør-Odal and Vinger to Eidskog.
The last time the Swedish forces attacked by way of Eidskog was in 1814 when Maj. Gen. Carl Pontus Gahn crossed the border and marched towards Kongsvinger Fortress.
[1] The importance of the route was strengthened with the opening in 1862 of Grensebanen, the Kongsvinger Railway Line which connected Oslo to Stockholm.
