The parish church of Monterosso, built in the 14th century in the Ligurian Gothic style. The façade is striped in alternating courses of dark green marble and white stone — the same visual rhythm you see in Genoa's most important churches — and the interior is cool and dim after the brightness of the caruggi outside.
The rose window above the portal is particularly fine. Inside, the church holds several works of modest art and a generally serene atmosphere. Worth stepping into even if you're not church-hunting — it's the geographic and social heart of the old town, and the square in front of it fills with village life on summer evenings.
