Pink Floyd Belgium 1968 Promo Films - Location question

I'm looking for information regarding the locations for the Pink Floyd promo films that were made in Belgium, 1968.

The main attraction is the famous Automium, which I know is still there in all it's glory, but I'd like to know if the following locations also still exist.
They all seem to be in close proximity to each other, and all have the Automium in the background, but are they still there too?

The first is the location in the "Scarecrow" promo, shown here...

 

The next location is the one in the "Paint Box" promo, seen here...

 

The final location is the one in this "See Emily Play" promo film...

 

I've studied all the footage, and to me it looks like the "Scarecrow" and "See Emily Play Locations" are part of the same area, and the "Paint Box" location may be above them. I can see concrete stairs in the "Emily" film that I'm guessing may lead to the "Paint Box" location.

Does anybody have any knowledge of this area?
I'd love to know if these locations still exist and if they are indeed all in the same area.
Any information would be greatly appreciated.

 

Atomium, not Automium.
Apologies for the bad spelling.

 

I've managed to find some more information in regards to the location.

Apparently, the footage is filmed on the remains of the exhibition '58, under the bridge, near the American Theatre.

I've checked on google maps and it looks like the American Theatre is gone but the base is there.

I can't find the bridge from the "Paint Box" film, or the oval pool with the ornament in it, as seen in the "Scarecrow" clip.

I'm wondering if these 2 locations are sadly long gone.
Hopefully not, but if anyone knows either way, I'd be interested to know.
