A little south from the city center is located the ancient Rocca, the fortress on a small promontory overlooking Garda (to the north) and Bardolino (to the south) from a height of about 300 meters.
The Rocca was probably built in the 5th century by the Lombards, as testified by many traces in the walls, but some finds date back to Roman times.
We can understand how important this castle was from two facts: first, it was named Garda, germanic for guard, meaning that at the time it had a great strategic importance; second, the name of the fortress then passed to indicate the entire lake, formerly called Benàco and now known as Lake Garda.
