Manscapsagreprep (Assassin's Creed: Valhalla)

In Norway, north of the player's settlement, there is the settlement of Manscapsangrep (p.. called XD). It has a house with "yellow" (from the category of "state" if you know what I mean) a loot with two doors locked from the inside, windows NO. It's NOT a good thing. Secret and not secret entrances NO))) The question to those who found this settlement I mean - how to get there XD? I've already broken my brain.
