Santa Maria Assunta Church, church in Cologno al Serio, Italy

Santa Maria Assunta Church is the parish church of Cologno al Serio, built from 1720 and opened for worship in 1745, with a facade added between 1753 and 1756. Its plan is rectangular outside but elliptical inside, formed by shallow curved side chapels; the single nave is divided into six bays by marble pilasters with Corinthian capitals. The facade, designed by Giovan Battista Caniana, has three tiers linked by volutes and niches holding statues of Saint Francis and Saint Charles Borromeo by Giovanni Antonio Sanz.

A church at Cologno al Serio is first documented in the 13th century as a dependency of the Ghisalba pieve and became a parish church in 1302 by decree of Bishop Giovanni da Scanzo. The bell tower was built in 1470. The old building was replaced: the first stone of the new parish church was laid on 2 October 1720, it opened for worship in spring 1745, the facade was built between 1753 and 1756, and the church was consecrated on 13 September 1767.

The church is dedicated to the Assumption of Mary. Its first altar on the right is dedicated to Saint Eurosia, whose marble altarpiece was designed by the Cologno architect Giovanni Allievi in white Carrara and red French marble. The third altar, in Baroque style, holds a painted panel of the Last Supper taken from the older parish church that was demolished.

The church is centrally located in Cologno al Serio next to Piazza Cardinale Agliardi and is easily reached on foot. It is open during services and certain feast days, and visitors are welcome to enter to view the architectural and artistic details.

The bell tower stands on the remains of an ancient medieval tower, and the church's exterior facade was made by Bergamasque sculptor Giovanni Antonio Sanz. In its two niches are his statues of Saint Francis and Saint Charles Borromeo, while the main portal's fronton is in Zandobbio marble, flanked by stone statues of Moses and Aaron.
