Lake Orta is a lake in northern Italy, west of Lake Maggiore.
It has been so named since the 16th century, but was previously called the Lago di San Giulio, after Saint Julius (4th century), the patron saint of the region.
Its scenery is characteristically Italian, while the San Giulio island has some very picturesque buildings, and takes its name from the local saint, who lived in the 4th century.
