Lisbon, the capital of Portugal, is located on seven hills near the Tejo River. In spite of the hilly terrain, the city can be explored on foot or by using the hill elevators known as "funiculars." The longest bridge in Europe and some of the world's oldest neighbourhoods are located in Lisbon, which is one of the least expensive major cities in Europe. The cultural identity of the Spanish capital of Madrid is reflected in the dramatic struggle of life and death portrayed in the bullfighting ring, the charismatic flair of the flamenco dancer and the relaxed, genial atmosphere of the tapas bar, which serves as extended home to many Madrilenos."
