Siena is unusual in several respects. Notable are its relatively narrow, curving streets. The major streets appear to follow the ridge lines, with minor streets falling away on either side. I believe that this is one such side street.
Again, we have a gate framing a view, this time of the principal campanile in Siena. The foreground street curves gently back and forth but does not disappear around a corner for some distance. In fact, just as it disappears, it leads the eye to another gate at the foot of the hill.
To pick a nit, the dormer roof that intersects the line of the campanile should be trimmed back until it no longer cuts the campanile from this vantage point - here again, the photographer has chosen the best spot.
