Pieve di San Pietro in Trento, Romanesque church in San Pietro in Trento, Italy.

Pieve di San Pietro in Trento is a Romanesque church featuring three naves separated by masonry pillars that lead toward an elevated apse positioned above a crypt constructed in oratory style. The interior displays an asymmetrical layout with irregular angles, making the structure architecturally distinctive.

Construction of the church dates to the 6th-7th century, and it first appears in written sources in 977, cited in the Archbishop's Archive of Ravenna. In the 17th century works gave the building a Baroque appearance, with the facade and side-aisle walls raised and two exedrae opened in the facade. Twentieth-century restorations, begun in 1912-13 under archpriest Giuseppe Rambelli and continued in 1923-27 under Secondo Proni, aimed to restore the original forms.

The name 'in Trento' refers to the church's location at the thirtieth mile of a Roman land division system that organized the surrounding territory. This naming choice reflects how closely the settlement was tied to ancient Roman infrastructure and planning.

The building underwent major renovations in 1946 that included lowering the floor and installing drainage channels to prevent water damage to the interior. These improvements protect the structure and make visiting more comfortable year-round.

The structure exhibits an unusual geometric shape with a scalene quadrilateral plan where only the angle between the facade and left wall forms a right angle. This uncommon architectural feature resulted from the builders' deliberate choices in adapting to the available space or site conditions.
