The night, not sleeping city of Madrid
Autumn bridge among the houses
Sunset breaks through the thickness of buildings
Pagoda surrounded by cherry blossoms
Natural sunset among trees and sun
Rays of the sun and autumn park
A building with many windows and a porch
Math formulas on the black steps
Back to the ancient world
Two sides of a crazy world
Images of large geometric objects on a bright blue background
An ancient fortress built on a rock
