Hello, it is Hitoritabi Mile.
It is remains of destination Pompeii tour of the trip the next day.
I wait for pickup early in the morning in a lobby and I change to a trailer bus and leave. From Rome via Naples to Pompeii. When stand in remains; there is the world of the different dimension. Across the space-time of 2000, life at the time revives.
A guide reminded that a road was slanted gently of it. It is for drainage. I was able to realize ancient Roman technical standards. (the Mt. Vesuvius volcano where I saw the photograph from Pompeii)
