💡 Did You Know…?
Local legend says the castle was connected by an underground secret passage to the nearby Church of St. George, used for quick escapes during sieges. Historically, it was home to an important writing and miniature school in the Middle Ages, linked to the Benedictine monastery that once stood here. During restoration work, fragments of 14th-century frescoes were discovered, now preserved at the Diocesan Museum in Bressanone. An interesting detail: the name ‘Sonnenburg’ means ‘castle of the sun,’ and the structure’s orientation actually captures sunlight for much of the day, creating unique light plays on the ancient stones.
