Porta Leoni (Lions gate) was one of the roman gates of the town.
The remains you can see now are more than 2,000 years old. The manufact is dating back to the late republican period (40/50 B.C.)
A first masonry facade (still readable behind the newer one) was covered with the much more scenic marble decoration you can see now in foreground. The remaining arch is one of the two the gate had, looking inward. Two towers were guarding the outside gate: you can see the basement of one of them in the open-air excavations that demonstrates well how the level of the street was elevated after two millenniums.
If you enter the bar just south, you can see a rest of anc ancient wall (with probably only few remains of the original roman stones) lined up with the external side of the towers... Just were it was 2000+ years ago. See pict #4
There is another roman gate, better preserved... Porta Borsari. Tip in progress
This Roman gate, dating back to the middle of the 1st century BC, gets its name from the sarcophagus surmounted by two lions that today is located in front of it. It belonged to the circle of old city walls and was subject to many changes over the first century after its construction. In the part existing today, hidden by the adjacent building and under the street which is visible from the surface are the remains of one of the two polygonal towers.
Porta dei Leoni (the Lion Gate) another monument bequeathed by the Romans, dating from the middle of the 1st century B.C. It was once part of the ancient city walls, and was drastically altered about a hundred years after its construction.
It consisted of two arches topped by a tympanum and flanked by columns, above which rose a series of arched windows, and finally a large exedra.
This gate, which is one of the most precious mementos of Roman Verona, was much admired by the artists of the Renaissance period for its perfect proportions and the beauty of its ornamentation.
