This town, anciently called Constantia or Cosa-dia, is pleasantly situated among meadows and rivulets about five miles distant from the sea. By the remains of a Roman aqueduct, and other ancient ruins, it appears to be a place of great antiquity. It is the see of a bishop, suffragan of Rome; and has a magnificent cathedral, esteemed one of the finest pieces of Gothic architecture in Europe.
