Santa Giustina, Romanesque church in Monselice, Italy.

Santa Giustina is a Romanesque church in Monselice that features thick stone walls with rounded arches. The building displays symmetrically arranged windows on its facade and preserves religious artworks inside.

Santa Giustina was built in the 13th century on the slopes of Colle della Rocca, replacing the earlier parish church on the summit, which was demolished to make room for the Mastio Federiciano. It served as Monselice's cathedral until the 20th-century construction of the Cathedral of San Giuseppe Operaio. A prothyrum was added to the facade in the 15th century.

Locals call it the "duomo vecchio", the old cathedral, since it served as Monselice's cathedral until the 20th-century Duomo di San Giuseppe Operaio was built. Inside, religious works span the 13th to 18th centuries, notably the Polittico di Santa Giustina and bas-reliefs attributed to Pietro Baratta. The church is dedicated to Giustina of Padua, a Christian martyr saint.

Santa Giustina stands on the slope of Colle della Rocca, below the Mastio Federiciano, so it is reached on foot along the climb from the town centre. The facade faces the hill and is entered through the 15th-century prothyrum, the porch added in front of the portal.

The church's silver liturgical chalice, the Calice di Santa Giustina, left the building's treasury and is now held at the Museo diocesano di Padova, so the vessel visitors might expect to see here is kept in the diocesan museum of the provincial capital.
