The parish church of Sant'Eugenio is the most prominent building in Altare's historic centre, its baroque facade flanked by two matching bell towers in a composition that is relatively rare in Ligurian ecclesiastical architecture. Built in the first half of the 17th century, it replaced an earlier Romanesque church founded by Benedictine monks, though the old Romanesque bell tower was retained and still stands.
The interior is modest but contains some fine carved woodwork and altarpieces accumulated over the centuries of the town's glass-guild prosperity. The church faces onto a small piazza that, on weekend mornings, functions as an informal meeting point for the town. It is a five-minute walk from the glass museum and a logical addition to any visit.
