My main Valheim-playing associate, the same person who hosts our server when it is running, and I built a nice castle on the side of a mountain. It sits right at the edge of where the “Meadows” biome meets the “Mountain” biome, so we had to do a lot of work to keep it properly heated and safe from the various nefarious beasties of the mountain tops. There are a few exposed areas, but all intentionally so. One is the top portion of half the structure, set up as a landing with decorative crenellations looking over the approach up the side of the mountain to the castle’s main door. Much of the view is obstructed by trees or the rising slope of the mountain behind us, but it is a comfortable place to stand and greet anyone who might approach.
