- Hillared Gastyr
- Chest x 11
- Chest (Average) x 3
- Lord Gastyr's chest - contains the Letter from Lord Erran Gastyr, related to the side quest Brun the Bard
- There are 2 locked doors on the western side of the dungeon, which is not related to any quests shown above.
- There seems to be the "Gastyr Key" in the game file, it's just a guess, but didn't appeard in the actual game, making those two doors totally inaccessible. If my theory isn't correct, and there's an actual way to open these two doors, add another notes, please. Choi Seungmin (talk) 12:03, May 13, 2013 (UTC) Anonymous
- There is a chest behind one of those doors...
- There are two pressure plates in the prison where one Prismere troll is caged (Hard Lock). The pressure plates do not appear to have any purpose.
- You can find the Cuirass and the Greaves of Bolgans' Bane Armor Set inside Castle Gastyr.
