Santa Sabina is an early basilica (5th century), with a classical rectangular plan and columns. The decorations have been restored to their original modesty, mostly white. Together with the light pouring in from the windows, this makes the Santa Sabina an airy and roomy place. Other basilicas, such as Santa Maria Maggiore, are often heavily and gaudily decorated. Because of its simplicity, the Santa Sabina represents the crossover from a roofed Roman forum to the churches of Christendom.
Santa Sabina was built by Priest Petrus of Illyria, a Dalmatian priest, between 422 and 432 on the site of the house of the Roman matron Sabina, who was later declared a Christian saint. It was originally near a temple of Juno.
