[Illustration: PLAN OF FOUNDATIONS DISCOVERED ON THE RIVA NUOVA, ZARA]
S. Domenico (which no longer exists) was of somewhat the same character; but the choir was without dividing walls, and thus became an upper church. It was only 21 ft. square and had three columns on each side, the last close to the wall. The vaults were domically quadripartite, springing from pilasters which rested on the caps. The arcade was round-arched, the central and right-hand apses were square-ended, and the left had a semicircular niche. The under church was wagon-vaulted without architectural features. The foundation of a chapel was found on the Riva Nuova with five niches of a six-niched circle and an entrance passage in the sixth, which turned at right angles to the north to reach the street. In the angle thus formed between the entrance and the main building a sarcophagus stood. This circular-niched plan occurs elsewhere in Dalmatia, as in the baptistery here, and SS. Trinita at Spalato, and the dimensions are generally so nearly the same as to suggest some common original design. S. Pietro Vecchio is considered to be the oldest church in Zara. It is now desecrated, but was used as a sacristy to the fourteenth-century church of S. Andrea, belonging to the Fishers' Confraternity, the sixteenth-century apse of which projected into the nave as far as the first pillar. It was cleared out by order of the Central Commission in 1886. It is about 38 ft. long by 19 ft. broad, and is built of ancient fragments with very little architectural character. One of the two columns bears a Roman inscription, and both have crosses cut in them. One of the caps is a damaged antique; the other is an antique base upside down; neither column has any base. The church is an irregular rectangle in plan, divided into two naves which end in apses by two pillars and a pier. The pilasters are not upright, the arches are deformed, and the two altar niches have half-cupola vaults on a rectangular plan, with arches thrown across the corners. There are two original doors, both built up. The pier between the two apses has a round-arched niche in it. The church is mentioned in 918 in the will of Prior Andrea.
