This one was rather difficult to pin down. And why do the vehicles appear to be in a river bed or ravine, anyway?
The hills on the horizon are near Aprilia, and we can see Lanuvio in front of them. Using parallax, and then using photographs of these hills courtesy of Google Street View, we find ourselves at a quarry on the outskirts of Aprilia. The Via Isarco runs through the quarry, answering our question.
Although quarrying has changed the shape of the landscape in modern times, and the road itself is moved, we can use photos from 2002 to find the old road and the olive groves behind the Tiger - identified by the direction of the lines of trees in them. And using parallax again, we find that there is only one possible place on the old road where this Tiger could be.
We've always listed this one as being near Poggibonsi.
I don't know the source of this information, but it's repeated online that we're at Highway 6 near Poggibonsi, 20 miles south of Florence.
This is slightly problematic.
The nearest "Highway 6" to Poggibonsi is 22km away. Granted, soldiers are not exact when they note the location of a photo, but this particular highway leads into Siena and it's odd that anybody would associate it with Poggibonsi.
(Modern Italian highways retain their WW2 numbers.)
Another problem is that I simply cannot find a spot in Highway 6 that closely resembles the photos.
I also searched other roads close to Poggibonsi. I found three locations that looked similar to this, but none of them had a roadside ditch, and this Tiger is clearly sitting in a ditch.
But the biggest problem with the Poggibonsi location is a photo of this Tiger that we noticed on Ebay two years ago. This was written on the back;
In no way can Highway 6 be described as the "road to Rome". It is 200 kilometers north of Rome.
A person named Marco Marzilli posted different information for this Tiger. I am currently asking him where his data comes from.
He said it was "on the road between Cori and Giulianello"
Looking at the various photos of this Tiger, it is not an easy one to locate. There are just a few features; the road; the shadows which tell us we're looking approximately north; a ridge of slightly high ground to the right of the road, not very far off; and a peculiar mound on the right side of the road almost immediately behind the tank. There is also a suggestion that the road bears to the right, curving around the big ridge. And finally, the Tiger is in a substantial ditch.
I have exhaustively searched the Cori-Giulanello road and there is exactly one spot that could be this. It has a ridge and a mound. The Google camera unfortunately doesn't hit the exact spot;
The mound is in fact the spoil resulting from the creation of a drainage tunnel under the road. After scanning roads here and at Poggibonsi, I can tell you this is a very unusual feature.
If this is the correct road, then this is the correct spot.
Well, Chris proved me wrong on that idea. Unpublished photos show another Tiger destroyed nearby. So I went looking again.
My problem was the railway station in the photo. It has disappeared from the earth without trace. So I ended up at the most similar surviving station instead. I didn't expect two battles near a railway line.
Now, the other photos show the hills behind Velletri, which told me the approximate area to look in; and they show electricity pylons which still exist. Using a few other cues I found a spot which I am 100% sure of.
The battle must be 29 February 1944, when 4 Tigers were lost.
