Located to the north of the town, near the north entrance to Salvatierra, the church of Santa María is a temple-fortress that once formed part of the wall. It was built between the late 15th and early 16th century on top of an earlier church, and has excellent stalls. It belongs to the late Gothic.The core is rectangular, with three naves. The central nave stands out, wider and taller than the rest.The sacristy is from the late 17th century, spacious, simple and with a beautiful balcony. The main entrance is Gothic, from the early 16th century, and is topped by a 17th century steeple.
Inside, the front of the wonderful, richly decorated Plateresque choir is dominated by a large crest of Emperor Charles V. The main altarpiece is a masterpiece by Renaissance artist Lope de Larrea.The church of Santa María also has outstanding images such as the Virgin of the Rosary, Mary Magdalene and Andra Mari de Sailurtegi. The organ is an outstanding piece from 1806, by Manuel Antonio de Carvajal.
References:The Basilica of Santa Maria in Trastevere is one of the oldest churches of Rome. The basic floor plan and wall structure of the church date back to the 340s, and much of the structure to 1140-43. The first sanctuary was built in 221 and 227 by Pope Callixtus I and later completed by Pope Julius I.
The inscription on the episcopal throne states that this is the first church in Rome dedicated to Mary, mother of Jesus, although some claim that privilege belongs to the Basilica di Santa Maria Maggiore. A Christian house-church was founded here about 220 by Pope Saint Callixtus I (217-222) on the site of the Taberna meritoria, a refuge for retired soldiers. The area was made available for Christian use by Emperor Alexander Severus when he settled a dispute between the Christians and tavern-keepers.
The church underwent two restorations in the fifth and eighth centuries and in 1140-43 it was re-erected on its old foundations under Pope Innocent II.
