Sant'Andrea, Romanesque church in Montedivalli, Podenzana, Italy.

Sant'Andrea is a church with three naves ending in three apses; the small right apse is hidden inside the Baroque bell tower. Its irregular plan and six reused columns of different heights, with mismatched capitals, support round arches. The exterior is clad in large squared stone blocks, and the apse has hanging arches with carved corbels.

The church first appears in historical records in 963 through an imperial diploma issued by Emperor Otto I. By 1148, according to a papal privilege from Pope Eugene III, it served as the mother church overseeing four smaller chapels in the area.

The six columns dividing the three naves carry mismatched capitals, reused from older structures; their bases differ in height to level the arches. A small relief on the left facade shows a figure in a long tunic holding a tau-shaped staff, identified as Venanzio, bishop of Luni, by comparison with Luni coins.

The church stands on a hilltop above the Val di Vara, reached by a climb from the hamlet of Montedivalli. It was closed for ten years for restoration work and reopened on 11 December 2011. The building has an irregular plan and a higher choir and altar than the naves, so watch your step inside.

The exterior of the apse is decorated with hanging arches on carved corbels, a feature rare in eastern Liguria, where Antelami-Genoese Romanesque forms arrived at the end of the 12th century. The same system appears at San Venerio di Migliarina and the oratory of San Bartolomeo at Ponzò.
