The Costa Chapel follows the same plan as the Della Rovere chapels but it was furnished by Portuguese Cardinal Jorge da Costa who purchased it in 1488. The most important works of art are the paintings of the lunettes by the school of Pinturicchio depicting the four Fathers of the Church; the marble altar-piece by Gian Cristoforo Romano (c. 1505); and the funeral monument of Cardinal Costa by the school of Andrea Bregno. The bronze and marble funeral monument of Pietro Foscari from 1480 is preserved here.
