It's really amazing how much the angle of depression (a technical term meaning the angle formed between a horizontal line and the line of sight when an observer looks downward at an object) effects our perception of depth. Here are two images of Miramar Palace (the orange building), built in 1893 at San Sebastián in Basque country, on the orders of Queen María Cristina of Austria, who used to spend her summers there. The white building behind it (with the black, conical roofed towers) is the diocesan seminary of San Sebastián (Elizbarrutiko Seminarioa), reconstructed in 1939.

In the first image, which is taken up close, the angle of depression is sharper, and the result is that the seminary appears to be almost directly behind Miramar Palace. In reality however, there is a distance of about a kilometre between the two landmarks, and there are plenty of buildings in between them. The second image approaches Miramar Palace from the same bearing (or azimuth), but from further away, and thereby the angle of depression is much gentler. This not only bestows a panoramic view, but allows us to judge the distance between the two architectural landmarks much better.
