Santa Maria Assunta, Religious monument in Mogliano Veneto, Italy.

Santa Maria Assunta is the main church of Mogliano Veneto, built on a Latin cross plan with three naves and an east-facing altar. The right nave is slightly wider than the left, a device used to improve acoustics. The 1838 ceiling frescoes by Sebastiano Santi show the Assumption and the four Evangelists.

A 997 foundation act records a baptismal church on this site, later destroyed in a late 9th-century Hungarian raid. Bishop Rozone of Treviso rebuilt it beside a Benedictine monastery; monks were replaced by nuns in 1075. The nuns left for San Teonisto inside Treviso in 1413, after which the parish gained autonomy.

The church is the seat of the vicariate of Mogliano and remains an arcipretale of the diocese of Treviso. From the 14th century two portionary priests, one for the area south of the church and one for the north, alternated weekly as acting parish priest and chaplain; the arrangement lasted until 1812, when only Antonio Ghirlanda remained after the death of Antonio Granzotto.

The church faces east, with the main altar at the eastern end and the entrance to the presbytery under a triumphal arch flanked by Sebastiano Santi's Annunciation frescoes. The right nave is slightly wider than the left, a device used in many churches to improve acoustics. Look up: the 1838 ceiling frescoes are also by Santi.

Of the original Benedictine monastery, only part of the 14th-century cloister survives beside the church. The nuns left for San Teonisto inside the walls of Treviso in 1413, and Pope Eugene IV had to intervene through the abbot of Nervesa to settle the dispute over which goods went with them and which stayed with the parish.
