There are several landmarks and unmarked locations that have been added to Craglorn, but are not normally accessible. Some locations can be found in Falkreath Hold, which is a dungeon with a vast exterior space based on TES V: Skyrim.
PlacesEdit
Falkreath WatchtowerEdit
Falkreath Watchtower is a watchtower west of Falkreath. It utilizes the basegame fort tileset. Contrary to its appearance in TES V: Skyrim, it appears to be intact. It is inaccessible by normal means.
South Shriekwind BastionEdit
South Shriekwind Bastion is a small Nordic ruin north of Falkreath. It is inaccessible.
