Granada, Spain, Saint Nicholas Observatory (Malaga San Nicolas). From the bottom of the mountain slowly climbed the steep hillside, step by step on the steps of the cobblestones laid by the Moors, and walked and looked at the long white houses on both sides. I unconsciously came to the Saint Nicholas Watchtower. The platform was small and crowded. It offers a panoramic view of the Alhambra, with snowy mountains in the Sierra Nevada.
