Fence in Salzburg

I have been traveling across Europe for the past few weeks and am tryithe e block to gathenough information aboutugh the architecfenceal pratoppling overs in each of the places I visit.

Here is the kind of fencing I saw in many parts of Austria.

The fences are of standard size and prefabricated. And here is how they are secured to the ground:

The prefab concrete blocks have holes deep enough for bottom of fences's post to go in and the block is heavy enough to keep the fence from toppling over.
