A series of gates surrounds the two centers of ancient, medieval Fez (sometimes spelled Fes). The principal axes link the center to the gates and a street surrounds the heart of the old city. The Kairouan quarter, which is longer, is crossed by an artery. Narrow, tortuous pedestrian streets, covered passages, stairs and numerous dead-ends make up the dense layout with few urban squares.

Barca d'Alva sits quietly along the Douro River, right at Portugal’s eastern border with Spain. Once the final stop on the historic Douro railway line, this riverside village remains relatively untouched by mass tourism.
