The Portico that provides access to the complex is in a simple style and is divided into two bodies. In the lower part, above the lintel, is a ceramic altarpiece showing us the dedication of the monastery: St. Jerome writing the Vulgate.
The upper part is developed with a triangular fronton, topped off with spheres on the corners, the centre of which is decorated with a stone coat of arms of the benefactor Alfonso of Aragon, grandson of King James II.
Features of note on the noble insignia are the coat of arms of the Crown of Aragon, for his grandfather King James II, and in the centre, lilies and labels for his grandmother, Blanche of Anjou, Princess of Naples; the rampant lion is the symbol of the Hieronymite order and the eagle’s talon with a sword represents the marquisate of Villena.
