- The Adige has a course of about 220 m., and, after the Po, is the most important river in Italy.
- 587 the river broke its banks, and the main stream took its present course, but new streams opened repeatedly to the south, until now the Adige and the Po form conjointly one delta.
- At the present day the frontier between Austria and the kingdom of Italy crosses the Adige about 30 m.
- Is the Adige, which, after pursuing a parallel course with the Po for a considerable distance, enters the Adriatic by a separate mouth.
