Astonishing Structure in Saudi Arabia

One of the most astonishing structures in Saudi Arabia is a network of 250 giant umbrellas that protect from the scorching sun and heat in Medina. They open early in the morning, providing shade and spraying cool water, and close in the evenings, transforming into lamp posts. They were primarily built for the pilgrims of the Masjid al-Nabawi mosque, and German specialists were responsible for their development.
