Costanza Alvarez de Castro was born in Rome in 1989, to an Italian father and a Salvadoran mother. After earning a degree in Economics for International Cooperation and Development, she decided to devote herself entirely to art and painting.

She began in set design for cinema and theater. In 2011, she assisted master set designer Jean Rabasse on the film Io e Te by Bernardo Bertolucci. It was Rabasse who later encouraged her to enroll at the Institut Superieur de Peinture Van Der Kelen et Logelain in Brussels, where Costanza distinguished herself as the top student of her class. In 2013, she returned to Rome to work on the painting of backdrops for the Opera House. Once her ventures in set design concluded, she decided to focus exclusively on easel painting.

Her first solo exhibition took place in 2015, curated by Valentina Moncada at Spazio Cerere.

During the same period, her work Melagrana was exhibited and sold at auction as part of the Sumarte2015 competition in El Salvador.

In 2016, she presented the portrait Carlo at the BP Award organized by the National Portrait Gallery, where the work was selected among the first four hundred out of over three thousand entries. That year also saw her second solo exhibition, Natura in Scena, held at Spazio Makemake, curated by Giovanni Argan, and the donation of the canvas Martinello to the Palazzo di Cosenza for a group exhibition curated by Roberto Bilotti for the six-hundredth anniversary of the death of Saint Francis of Paola.

In 2017, she created A Painting for Marguerite, a charitable initiative aimed at funding educational projects through art. Another solo exhibition, Giorno di festa, took place in Rome between December 2017 and February 2018 at Spazio Menexa.

Recently, Costanza has begun to expand her horizons by also dedicating herself to illustration for children’s books. Her artistic research continues, nourished daily by the talent and perseverance that have always distinguished her.
