Indre Østfold

Indre Østfold is a mostly rural countryside region north in the former county of Østfold county in Norway, noted for its mostly unspoilt nature and for its agriculture.

2020 five of the municipalities of Indre Østfold merged into the new Indre Østfold municipality at the same date as the Østfold fylke and neighbouring Akershus fylke merged with Buskerud fylke and became regions in the new Viken fylke (county).

Today the region consists of these five municipalities: It is located around 30 kilometers from Norway's capital Oslo, with the Europavei ("Europe Way" / European route) E18 as the main arterial road through the region, and several Riksvei national roads running through the area.

Haldenskanalen (The Halden Canal in Norwegian) is the oldest constructed water canal in the country[1] and has the highest continuous lock system in Europe.

The Indre Østfold region has played a central role in Norwegian history and has defence works from various periods.
