The Hieronymus monastery of Santa Engracia was built during the 15th and 16th centuries on the site of the Christian-Roman necropolis that held the two 4th century marble sarcophaguses preserved in the crypt.

The façade is all that remains of the Monastery that was built as a grand architectural site during the first half of the 16th century. It was founded by King Juan II of Aragón, in gratitude for having been cured of cataracts, and the work was continued under his son, Fernando el Católico, before being completed during the reign of Emperor Carlos V. The façade was seriously damaged during the Sieges and restored by the sculptor Carlos Palao, who repaired some figures whilst entirely replacing others.

It is one of the earliest and finest Renaissance style façades. Most of the work was carried out by Gil Morlanes the Elder but it was finished by his son. Its altar-façade reflects both the patronage of the monastery and its origins.
