Casale Monferrato sits on the right bank of the Po, an old Gonzaga capital that still feels much larger than its 34,000 inhabitants. The brick-walled Castello dei Paleologi anchors the town centre, and the Duomo of Sant'Evasio, founded in the eleventh century, has one of the most unusual narthexes in Italy — a low forest of arches and vaults rather than a single entrance hall.
The town is most famous for its hidden gem: the Synagogue of Casale Monferrato, tucked behind unmarked doors in the old Jewish ghetto on Vicolo Salomone Olper. The interior, redecorated in 1866, is an exuberant Rococo space of gilded stucco and painted walls, one of the most beautiful synagogues in Europe. The attached Jewish museum documents one of Piedmont's oldest Jewish communities.
