Locations of all cairns in the game. Each cairn found will give you a free skill point for all characters. There are two Steam achievements associated with these cairns, one for finding all of them in Denmark and another for finding all of them in Britain.
This should probably be the first one you find, it’s in your village by the graves on the eastern edge of the screen.
This one is on the premises of the Erlingr farm.
This one is in the forest near Skjern.
This one is near the burial mound in the eastern village.
These three can be found in Ribe.
In the Ribe swamp.
Found in Perth.
Found in Scarborough.
Found in York.
This one is located in Yngilwood. The only way I know of to unlock this location is to be invited there by Wada in York, which as far as I know always happens after meeting with/confronting King Osden. There might be other ways to unlock it, so let me know if you’re aware of any.
This cairn is located on the premises of the ruined Roman fort. As far as I know, the only way to unlock this location is by accepting the quest from the Bishop in York. Wada will ask you to undertake that quest on his behalf after you meet him in Yngilwood, but I don’t know if it’s possible to take it otherwise.
Old Mac Daimnall had a farm, ee-aye-ee-aye-oh. And on that farm he had a cairn, ee-aye-ee-aye-oh.
This location is part of a quest you accept from Caustantin, in a manner of speaking.
This is at Seahenge. It’s a very small area with very little in it, so it’s very easy to find the cairn, but to unlock the location you’ll need to take the second quest from Caustantin, the Pictish King.
