The stolen painting in the "Canvas the Castle" quest in The Elder Scrolls IV: Oblivion is hidden in Castle Chorrol's West Tower. Specifically, you can find it behind a set of crates in the West Tower, where there is a trap door in the floor leading down to a secret lower chamber containing the painting
. To summarize the key points about the painting's location and the quest:
- The painting is found by going to the West Tower of Castle Chorrol.
- Behind some crates in the West Tower, there is a trap door in the floor.
- Descending through this trap door leads to a hidden area where the stolen painting is located.
- The painting depicts a chapel and serves as a crucial piece of evidence in the investigation.
- Additional clues related to the painting and the thief are found in Chanel's room (painting supplies in her lectern) and the Dining Hall (paint stains on the carpet)
This quest involves investigating the theft of the painting, interviewing suspects and witnesses inside the castle, and gathering evidence before making an accusation
. The painting itself is a key item found in the secret chamber accessed via the trap door in the West Tower behind crates
. Thus, the painting is located inside Castle Chorrol, hidden in a secret chamber beneath the West Tower.
