Magnificently sited on a series of hills running down to the grand Tagus River, Lisbon is one of the world's most scenic cities. Beautiful unexpected views are found at every turn down its colorful, picturesque streets, and especially from strategically-placed viewpoints or terraces at the top of each hill. The city has an unpolished, seductive appearance; an effortless beauty with captivating details such as cobbled designs, tiled façades, and pastel-colored buildings blending together to give it a singular atmosphere now lost in so many other cities
