The parish church of San Martino in the hamlet of the same name is Stella's principal church, containing two significant works of Ligurian baroque art. The wooden statues by Anton Maria Maragliano — the most celebrated Genoese sculptor of the late Baroque period, who worked in the last decades of the 17th and early 18th centuries — are among the finest examples of his polychrome wood sculpture outside Genoa itself.
The 18th-century fresco inside the church depicts a religious scene in a style typical of Ligurian decorative painting of the period. The church opens for masses and sometimes for visits; ask locally if you find it locked. The hamlet of San Martino itself is a small cluster of stone houses on a ridge with views across the wooded hills toward the coast — a short walk from the other hamlets of Stella.
