Agdenes is a municipality in the county of Sør-Trøndelag, Norway.
The shield was adopted in 1991 as the Agdenes coat of arms; the red colour represents strawberries and/or the blood of Eirik Bloodaxe.
This was because the area had been without road connection, and once the road was built, it was built in the direction of Snillfjord and it was hence logical to vote for the transfer.
In the comparison of the achievements of King Øystein and his brother, King Sigurd, Øystein claims that he built the harbour whilst his brother was on a journey.
Agdenes bay is not a good natural harbour, but its geographical position can scarcely be better if the desire is to establish a control and defence post.
Trondheim or Nidaros as it was called then, functioned at this time as both a trading and a political centre in central Norway and the harbour was built during the period when civil wars still occurred and central Norway was still only somewhat loosely attached to the rest of the kingdom.
