Grottoes of Catullo

From Wikipedia: "Grottoes of Catullus is the name given to the ruins of a Roman villa which was built at the end of the 1st century B.C. and the beginning of the 1st century A.D. at the northernmost end of the peninsula of Sirmione on the southern shore of Lake Garda.^[1]"
This big house was built on 3 levels, and it had 2
 ^{big lateral covered porches} for each floor. The 
1st floor spaces were the ones occupied by the 
Landlord family. In fact, on this level there were 
the tubs area, the atrium, the office of the 
householder, the dinning room with triclinium 
and the terrace. At the intermediate level probably
there were warehouses and other service 
structures for the house such as the furnace or
the big tank for the water.
At the bottom level there were probably shops 
and small taverns.
Here it is how the building was to appear

In the following picture you can see what remains of the 3rd level of the house. On the left you can see the walls of the thermal swimming pool of the Spa area. On the left you see the covered arcade that was leading to the terrace.

In the next one you see the terrace area from North to South. As you will notice the terrace is collapsed and you can see just the walls behind it, where the bed rooms were.

In this other one you see the arcs of the mid level covered arcades

In the following picture you can see the flight of steps that leads to the ground level

Next one shows the corridor and his bed rooms on the right 

And the last picture shows some of the arcs of the lower lever covered arcade
