A village of Venetia, Italy, in the province of Padua, 3 m. to the S. W. of Battaglia. Pop. (1901) 1 573. It is chiefly famous as the place where Petrarch lived his last few years and died in 1374. His house still exists, and his tomb, a sarcophagus supported by four short columns of red marble, stands in front of the church. Near Arqua, on the banks of the small Lago della Costa, is the site of a prehistoric lake village, excavations in which have produced interesting results. See A. Moschetti and F. Cordenone in Bollettino del Museo Civico di Padova, iv. (1901), 102 seq.
