San Michele, Trino, Medieval church in Trino, Italy

San Michele is a Romanesque church outside Trino, on a site once encircled by two branches of the Po. Its 18th-century facade has a pronaos before the entrance, and the interior has three naves, the central one raised above the side aisles.

The pieve's written records date to the 10th–11th centuries, though the site was inhabited and walled since Roman times, suggesting an earlier sacred building. The church took its sober Romanesque form in the 12th century and kept it through later works. It lost importance as the settlement shifted to the area of the 13th-century parish church of San Bartolomeo, yet popular devotion kept the old pieve from being abandoned.

The name "in Insula" survives from when the site was encircled by two branches of the Po. The pieve stayed dear to popular devotion even after the town shifted toward the 13th-century parish church of San Bartolomeo, and it was never fully abandoned.

The church stands outside the built-up area of Trino, on a site still called Insula because two branches of the Po once surrounded it. It is reached by leaving the town and taking the road toward the countryside, by car or public transport. Check opening times before setting out, as they vary by season.

Some of the frescoes inside date back to the 12th century and show techniques used by medieval Italian painters of that era. These paintings reveal what artistic subjects and styles were valued in this small town centuries ago.
