Telephoto compression effect

I took this a while ago, but it really shows how dramatically a telephoto lens can compress a scene. The office buildings in the background are more than FIVE MILES away from the observatory building in the foreground. This was taken at 300 mm on a crop sensor camera, so is about equivalent to a 500mm lens on a full frame. I was probably about 1/4 mile from the observatory when I took this.
In this shot the office buildings are around 20 times the distance of the observatory, if the same shot was taken with a normal lens you'd be ~1/40 mile to get the same framing on the observatory while the office blocks are still ~4 3/4 miles away a very different ratio.
Admittedly the framing of the telephoto encourages the more distant viewpoint with greater compression - giving rise to the view that the telephoto is responsible. Taking the shot with a normal lens from the same position would show the same compression, but the image would probably be rather unimpressive!
I suspect the terrain here has also helped the impression of compression - but in any event it's a great shot!
Bingo! Great explanation. Its not the lens that causes the compression effect.
