The Roman remains, Verona
Some of my friends, when visiting Verona, couldn't find the location of Porta Borsari. In fact, it looks like hidden in the structure of the newly build houses that are surrounding it. You can't miss it approaching from the direction of Castelvecchio, by Corso Cavour street.
Porta Borsari is Roman Gate from 41-54 d.c., you can approach to it from Corso Cavour or Corso Porta Borsari which is right on the opposite side.
You may think that the Roman Verona is showing it all with the Arena, the roman theatre, the gates.
Well, there is a lot more, but it is just difficult too see.
A lot of the basements of many buildings of Verona (normal buildings) have roman foundations. Some have the remains of a roman "domus" on their basement.
Many of those remains are hard to see, here is an exemple, from the basement of the Banca Popolare di Verona, in Via San Cosimo, just face to face with the #9.
You can see, from the street if the courtains are up, the "impluvium" of an ancient roman house: That was the pool placed in the first atrium, colleting water from the roofs.
See the picture, and forgive me for the quality. The heavy glass makes it hard to take pictures from outside.
Other accessible basement with roman remains (that i know of) in the city center are:
1) the underground congress hall of Unicredit in Via Garibaldi (2 of the main walls are roman)
2) the basements of the restaurants MAffei (Piazza Erbe) and 12 Apostoli, just south from the square. Ask the staff to see them if you eat there, or you will lose something special! (BTW The HAVE to show you if you ask... It's a law!)
3) the forniture shop just behind the Arena (a few meters behind "the wing")
Recent thorough archaeological digs, the results of which are clearly visible from the street, have revealed the base of the ancient Roman gateway, extensive sections of the original road surface and the polygonal base of one of the great corner towers, defending the gateway.
Just as in Rome Verona has Roman excavations taking place - of a roman theatre. Came across these remains just by the Leoni gate in in Via Cappello. They are right in the middle of the road and just beyond are some nice cafes for a drink here too - granites - crushed iced drinks of various flavours - are popular here.
Along the river bank on the same side of the river as the gardens is the entrance to the Roman theater. This patch of green in the city is worth a quick visit as it contains the ruins of a Roman theater. The stage and seating area is still there and being tucked back with trees it can be a great place to go when you are in need of seeing something green. It offers a great piece of Roman history in Northern Italy.
