Sant'Andrea Apostolo, Catholic church in Iseo, Italy

Sant'Andrea Apostolo is a church in Iseo that blends Romanesque and Neoclassical features. The interior contains three naves with barrel vaults supported by Corinthian columns, while the facade includes a bell tower with small ornate windows and wall niches.

The church was founded between the late 5th and early 6th century by Bishop Vigilio, replacing earlier Roman structures on the site. In the 14th century, tombs were added, and later architect Rodolfo Vantini carried out significant renovations that modernized the interior.

The church is dedicated to Andrew the Apostle, and its full name is Pieve di Sant'Andrea. In the same square stand the church of San Giovanni Battista and the former Oratory of the Disciplinati of Bergamo, so the area around the facade holds several religious buildings. The cenotaph beside the bell tower bears an inscription honouring Giacomo III Oldofredi.

The church stands on the same square as the church of San Giovanni Battista and the former Oratory of the Disciplinati di Bergamo, so the three can be visited together. The bell tower rises in the centre of the facade, with the Oldofredi funeral ark walled in to its right. The interior was renovated by Rodolfo Vantini between 1826 and 1840.

The walled funeral monument to the right of the bell tower honours Giacomo III Oldofredi, podestà of Milan, commander under Galeazzo Visconti and builder of Iseo's town walls. It was set into the church in the 19th century.
