The centre of the town, with its stone-paved streets, is picturesque, and the Piazza il Vecchietta is particularly interesting. The walk through Castiglione should include a visit to the Romanesque Church of S. Mary and Magdalena, which have been recently restored. Its facade dates back to the 13th century, while the apse is 1 century oldest; the bell tower is very interesting, too. Because of the number of works of art that it contains, the Church of Saints Steven and Degna was the most important religious building in Castiglione, even though its interior is not particularly interesting.
