a town of the Papal States, 12 miles S. by E. of Rome, on the declivity of a hill commanding an extensive prospect. The town itself is not in any way remarkable; but the beauty of the vicinity, interspersed with numerous elegant villas, and the salubrity of the atmosphere, annually attract numerous visitors from Rome and other parts. On the summit of the hill, above the town, are the ruins of the ancient Tusculum, the birthplace of Cato, and the favourite residence of Cicero. Frascati took its rise in the 13th century, after the destruction of Tusculum by the Romans in 1191. Many of the older houses date from the 13th and 14th centuries; and the church of San Rocco, formerly the cathedral of San Sebastian, and still called the Duomo Vecchio, was built in 1309. The new cathedral was completed in 1700, and contains a monument to Cardinal York, who was Bishop of Frascati, and another erected by the cardinal to his brother Charles Edward, the young pretender, who died here on 31st January 1788. The Villa Rufinella, which formerly belonged to Lucien Bonaparte, has within its precincts a hall called "Parnassus," on the slopè of which the names of celebrated ancient and modern authors are planted in box. One of the most splendid of the villas is the Aldobrandini; its grounds are adorned with numerous fountains and water works. Pop. about 5000.
