Castell de Canyelles is a 15th-century fortification in Canyelles, Garraf comarca of Barcelona, documented from 1478 when owned by knight Francí Terré. The castle's history extends back to 1191 through the Canyelles lineage, possibly built upon an older defense tower connected to the castle of Olèrdola. The preserved remains consist of a circular tower and wall fragment with five battlements, positioned beside the Church of Santa Magdalena. After restoration in 1858, the castle was donated to the Municipality of Canyelles in October 2025, ensuring its continued preservation and public access for future generations.
