This picture shows Barry at the memorial to Raymond Sommer who was killed there in September 1950.
By way of a contrast, this picture from Christian Huet's Un Sorcier, Une Equipe shows the monument in 1951. The leading cars are Trintingnant, Behra and Manzon.
The remains of the footbridge can still be seen:
The towers supporting the bridge look old, but the ramp is clearly more modern. I don't know what it was built for.
This shows Barry investigating the remains of a building which was presumably something to do with race control. There is a start/finish line painted on the road.
This picture shows the start/finish area looking down towards the final corner. We assumed that the area on the left was the pits.
It was a very peaceful place.
