How do people take pictures "holding up the leaning tower of pisa" or

Question:People go on vacation and take pictures where they somehow angle the camera enough to make it seem like they are touching the building, or holding it. What is this called in photography and how do you take a picture like that?
Here are some links to describe more specifically what I mean.

Cherry's answer is 100% correct. There is no real term for this style of photo, but in general terms, what you are seeing is known as SCALE. You are using objects of greatly varying size and placing them in the photo to give a distortion of scale. It is totally simple to do, but the person taking the photo does have to tell the person being photographed exactly where to stand and pose.

Remember, a photo is only two dimensional, whereas we see in three dimensions. Seeing the examples as shown in your links in person would not look at all like the photo, because our eyes can see the depth, but the camera cannot depict depth, so the illusion of the two varied scales looks as it does in the photo.

I don't know what it is called, but I can guess how it is done.

The photographer has to frame this particular photo carefully. And probably most important is there must be enough depth of field so the object in the background is in focus, samples of DOF (depth of field) that I am talking about is here:

left photo, large aperture (f 1.8), right photo, smaller (at 5.6). Could have been smaller (to f 16, and the house in the back might have been much sharper).

A short lesson in photography there.

Because the landmark would be so much larger than the person in the photo, obviously the person in the photo must be much closer to the lens. The person behind the camera must tell the model where to move or put their hands to give the illusion that they are 'holding up' the leaning tower of Pisa.
