CITTADELLA, a town of Venetia, Italy, in the province of Padua, 20 m. N.W. by rail from the town of Padua; 160 ft. above sea-level. Pop. (1901) town, 3616; commune, 9686. The town was founded in 1220 by the Paduans to counterbalance the fortification of Castelfranco, 8 m. to the E., in 1218 by the Trevisans, and retains its well-preserved medieval walls, surrounded by a wet ditch. It was always a fortress of importance, and in modern times is a centre for the agricultural produce of the district, being the junction of the lines from Padua to Bassano and from Vicenza to Treviso.
CITTÀ DELLA PIEVE, a town and episcopal see of Umbria, Italy, in the province of Perugia, situated 1666 ft. above the sea, 3 m. N.E. of its station on the railway between Chiusi and Orvieto. Pop. (1901) 8381. Etruscan tombs have been found in the neighbourhood, but it is not certain that the present town stands on an ancient site. It was the birthplace of the painter Pietro Vannucci (Perugino), and possesses several of his works, but none of the first rank.
CITTÀ DI CASTELLO, a town and episcopal see of Umbria, Italy, in the province of Perugia, 38 m. E. of Arezzo by rail (18 m. direct), situated on the left bank of the Tiber, 945 ft. above sea-level. Pop. (1901) of town, 6096; of commune, 26,885. It occupies, as inscriptions show, the site of the ancient Tifernum Tiberinum, near which Pliny had a villa (Epist. v. 6; cf. H. Winnefeld in Jahrbuch des deutschen archäologischen Instituts, vi. Berlin, 1891, 203), but no remains exist above ground. The town was devastated by Totila, but seems to have recovered. We find it under the name of Castrum Felicitatis at the end of the 8th century. The bishopric dates from the 7th century. The town went through various political vicissitudes in the middle ages, being subject now to the emperor, now to the Church, until in 1468 it came under the Vitelli: but when they died out it returned to the allegiance of the Church. It is built in the form of a rectangle and surrounded by walls of 1518. It contains fine buildings of the Renaissance, especially the palaces of the Vitelli, and the cathedral, originally Romanesque. The 12th-century altar front of the latter in silver is fine. The Palazzo Comunale is of the 14th century. Some of Raphael’s earliest works were painted for churches in this town, but none of them remains there. There is, however, a small collection of pictures.

CITTÀ VECCHIA, or Città Notabile, a fortified city of Malta, 7 m. W. of Valletta, with which it is connected by railway. Pop. (1901) 7515. It lies on high, sharply rising ground which affords a view of a large part of the island. It is the seat of a bishop, and contains an ornate cathedral, overthrown by an earthquake in 1693, but rebuilt, which is said by an acceptable tradition to occupy the site of the house of the governor Publius, who welcomed the apostle Paul. It contains some rich stalls of the 15th century and other objects of interest. In the rock beneath the city there are some remarkable catacombs in part of pre-Christian origin, but containing evidence of early Christian burial; and a grotto, reputed to have given shelter to the apostle, is pointed out below the church of San Paolo. Remains of Roman buildings have been excavated in the town. About 2 m. E. of the town is the residence of the English governor, known as the palace of S. Antonio; and at a like distance to the south is the ancient palace of the grand masters of the order of St John, with an extensive public garden called Il Boschetto. Città Vecchia was called Civitas Melita by the Romans and oldest writers, Medina (i.e. the city) by the Saracens, Notabile (locale notabile, et insigne coronae regiae, as it is called in a charter by Alphonso, 1428) under the Sicilian rule, and Città Vecchia (old city) by the knights. It was the capital of the island till its supersession by Valletta in 1570. (See also [Malta].)
