Santa Grata, Baroque church in Città Alta, Bergamo, Italy.

Santa Grata in Columnellis, also called in Via Arena, stands in Bergamo's upper town within the city's oldest Benedictine cloistered monastery. The name Columnellis refers to the columns of the outer portico of the earlier church, before the 16th-century restorations. A small Lombard-origin church, called the old one, survives inside the monastic complex.

Tradition attributes the monastery's founding in the 4th century to Adleida, wife of Lupo, duke of Bergamo, and mother of Grata; the church was then called Santa Mater Vetur. A document of 938 by the deacon Adalberto mentions vineyards "subtus monasterio qui nominatur Sancte Marie qui dicitur Vetere", repeated in acts of 953 and 971. In 1027 abbess Officia enlarged the monastery under the Benedictine rule, and on 1 May the relics of Grata were moved here in a procession led by bishop Ambrogio II. The present church was rebuilt from 1477 to a design by Leonardo Moroni and Alessio Agliardi, funded by the bequest of Arigino dei Capitanei di Mozzo.

The name Columnellis refers to the columns of the portico that stood before the 16th-century restorations. The monastery holds 71 documents from 1049 to 1791, including a 1049 bull attributed to Leo IX that was shown to be false, likely made to defend the nuns' properties against Maifredo de Martinengo.

The church stands in Bergamo's upper town on Via Arena, and the name Columnellis refers to the columns of the portico that preceded the 16th-century restorations. It belongs to a cloistered Benedictine monastery, so the monastic areas are not open to visitors. The 1477 rebuilding was financed by the legacy of Arigino dei Capitanei di Mozzo.

The name Columnellis refers to the columns of the outer portico of the earlier church, before the 16th-century restorations. Inside the monastic complex survives the small Lombard-era church called "vecchia", distinct from the nearby church later rebuilt as Santa Maria Maggiore.
