It was founded in the 9th century and became subject to theBenedictine Abbey of Santi Ilario e Benedetto, which was headquartered at the western edge of theVenetian Lagoon, in 989. Serious flooding resulting from a war between Padua and Venice resulted in the monks of Santi Ilario e Benedetto moving to their Venetian dependency. San Gregorio became the seat of the Benedictine community in 1214. Simultaneously, it also served some of the duties of a parish church and had a close association withSanta Maria Zobenigo.

In the mid-15th century it was rebuilt to the current appearance under design by Antonio da Cremona. An unsuccessfulCommenda investment in 1450, intended to finance the reconstruction, initiated a long period of decline, which would last until its ultimate dissolution in 1775. After the dissolution, the church briefly became aparish under the jurisdiction ofSanta Maria del Rosario. In 1807, during theNapoleonic occupation of Italy, the parish church was suppressed.^[1]

Deconsecrated, the church was converted into amint for refining gold, while the abbey building was converted to housing. The church was converted to an art restoration laboratory of the Superintendency of Archaeology, Fine Arts and Landscape for the Municipality of Venice and the Lagoon in 1960.^[2] The church still stores art as a depository of the Directorate of Museums but is functionally unused, and has experienced structural damage.^[3][4][5] In 2017, it was announced that San Gregorio was to become the main location of the Museum of Oriental Art, currently at theCa' Pesaro. However, as of 2025, the church remains disused. The abbey building which was converted to housing after 1775 has partially been converted to exhibit space, and host events for theVenice Biennale.^[6]

Canaletto painted some of his Venetian scenes from the first floor of the abbey building.^[7] The abbey'scloister has also been a popular artistic subject.^[1]

The church's main façade is situated on the eponymous Campo di San Gregorio, while the triple apse juts out into the Rio de la Salute. The attached abbey building, a quadrangle built around a small cloister, abuts theGrand Canal. Two bridges on either side of the triple apse cross the Rio de la Salute, making the abbey accessible to visitors to the Fondamenta Salute.

The abbey was originally constructed in a Venetian-Byzantine style, and gained its currentVenetian gothic appearance in the mid-15th century. The gabled brick façade is divided into three parts by fourlesenes and features anogival portal and rose window. Elongatedmullioned windows with ogival tops are used throughout the church, particularly on the tripleapse.^[8] The interior shows remnants of frescos and contains a notabletruss ceiling in the nave, while the apses have vaulted ceilings.^[5]

Views byCanaletto,Bellotto, and othervedutisti show that the façade's lesenes once rose into threeogee arches topped with statues and interspersed withpinnacles. This decoration has since been lost.
