A major oversight was not seeing the Roman theatre. I saw this postcard, but since the monument wasn't identified, I thought it was also part of the amphitheater and didn't know there was still a theatre there. I should have studied the itinerary better...
We passed so many churches that I'm not sure if we went by this one, but I remember that in front of another one we ate a typical sweet called Pasticciotto, which is delicious!
The cathedral is also amazing and despite the heat, the city is quite walkable which is good for seeing all the monuments.
The Basilica of the Holy Cross is probably the most amazing monument of the city
Parts of the Roman amphitheater are covered by other buildings and Piazza Sant'Oronzo
