The observatory should be located on the mountain. One can see more from the mountain top. Provided that clouds don't shroud it, otherwise nothing can be seen. Or nothing but ghosts and phantoms, but they are not interesting – any wind blow can disperse and sweep them away. Usually we are too close to the earth, to the ground, and too far from the sky. The mountain takes us away from the earth and closer to the sky. So, it's enough to climb the mountain and start to observe. Now we look down, now we look up. This alternate change is essential. Looking up or down too long makes us dizzy, which consecutively cause various deformations and distortions. Although deformed observations can also be interesting and bring us some important pieces of information, anyway not deformed and not distorted pieces of information seem more valuable. That is why it's good to move the head. Of course, looking forward is the safest, as well as the least deforming, but, quite strangely, not everything is happening in front of us, well! the majority of things and affairs is happening not in front of us.
For example, astronomic things and affairs usually happen above us. Not many of them happen right above the horizon so that we don't need to look up to see them. Fortunately astronomic affairs are considered here rather unimportant, so the observatory is equipped poorly. There are no telescopes, no measuring devices – what were they for if no measurements are made? There is no edifice deserving to be proudly named “observatory” – neither a giant stone circle, nor even more mysterious dome which could open like a shell, or turn like a monstrous eye on a movable stalk. However it would be untruth to say there is no observatory here. There is a MOUNTAIN here. It's enough to climb it and make observations. And if the light is too sharp, you have to protect them with your hand pressing the edge of the palm to the forehead, thus making a kind of peak over the eyebrows. If the things we observe are too horrible (the life of stars, suns, planets, moons and comets is full of horrible events), then it's enough to turn the palm down and put it on the nose. If we want to check whether the horrible events have ended (whether one galaxy has finally devoured another one) then we make a slit between the fingers to peep the universe.
That's all.
