Pieve di San Lorenzo, Romanesque church in Montiglio Monferrato, Italy

The Pieve di San Lorenzo is a Romanesque church beside the cemetery of Montiglio Monferrato, built of brick alternating with sandstone blocks. Its single nave is flanked by four round arches per side opening into semi-hexagonal chapels, and the surviving central apse shows two pilasters, a small window and a band of alternating brick and stone lozenges.

No document records the year the pieve was built; stylistic comparison with San Secondo at Cortazzone and Santa Fede at Cavagnolo places its foundation around the mid-12th century, in the Monferrato astigiano Romanesque flowering. Between the 13th and 14th centuries the population moved inside the fortifications of the nearby hill castle, and the church lost its role as a pieve, becoming the cemetery chapel it still is. The wooden roof collapsed and around 1850 it was restored with a barrel vault and semi-hexagonal side chapels; the facade was rebuilt in the 19th century and remade in 1955-59.

The name pieve denotes a baptismal church with jurisdiction over a district; after the 13th–14th centuries the building became and remains the cemetery chapel. Inside, capitals carry medieval imagery: two-tailed sirens, monstrous figures, birds holding grapes, and men wrapped in vine tendrils. A stone telamon of uncertain identity, once part of the old facade, is displayed among finds collected outside.

The church is easily accessible on foot from the village center and has enough interior space to explore at a comfortable pace. Visitors should watch for uneven flooring and plan to view the carved capitals during daylight hours when natural light best reveals their details.

The 18th-century square structures flanking the central apse are what remain of the side apses demolished in that period; they project from the perimeter almost like a transept. Inside, a telamon of uncertain identity, probably from the old facade, is displayed among finds from the exterior.
