The Cathedral of Santa María (Spanish: Catedral Vieja de Santa María), known as the Old Cathedral, is one of the two cathedrals in Salamanca, Castile and León, Spain. Founded by Bishop Jerome of Périgord, its construction began in the first third of the 12th century and was finished at the end of the 14th century, in Romanesque and Gothic style. It was finished thanks to the impulse given to the works by Bishop Alfonso Barasaque. It is dedicated to Saint Mary of the See (Santa María de la Sede).
