“Slowly the wind falls, and the still air begins to freeze. The solid eastern ridge is black; it has a bloom on it like the dust on the skin of a grape. The west flares briefly”.
J.A. Baker, The Peregrine

As the shadows cast by the sun grow longer, the air fills with midst and dust of a mineral scenery. The rocks that shelter the nest are sharp as knives. The land is arid and dry. It is a high cliff wall, that only a powerful hawk can reach. Their home is the sky, their haven are the rocks.

The scenery is indeed one of the movie's character, sharp, high and dangerous, it must cover 360°, so that the flights and fights in the sky can be filmed with the greatest freedom.
