There are several landmarks from The Elder Scrolls: Arena that have been recreated in ESO's version of Summerset, but are not normally accessible. They are shown on the map, but not named in-game.
PlacesEdit
Belport RunEdit
The island of Belport Run is located northeast of Karndar Watch. The island cannot be accessed but it can be seen from the shore.
Crystal TowerEdit
The only accessible part is the gatehouse. The zone version of the Crystal Tower has a different entrance compared to the Fields of Regret version.
