The tree-lined, elegant residential Vedado district dates back to the second half of the 19th century, but its present day appearance really took shape beginning in the early 1900s. After the end of the Spanish-American-Cuban war in 1989, US money began pouring into Havana from many sources and in many forms. Most of the affluent Cuban families of the period built large and prestigious residential estates and lavish mansions bearing opulent and impressive designs ranging from neoclassical, art deco, beaux arts and eclectic. The mansions line landscaped boulevards with huge promenades with statues and monuments, including the impressive inner city campus of the University of Havana. During the mid-20th century, a great deal of modern buildings were designed and erected, some financed by the mob and others by developers and financiers. Some of the greatest modern architecture in the world, both in quantity and design is on display throughout the Vedado district from its neon and incandescently lit 1950s movie theaters, modern hotels like the Capri and the Riviera, the Embassy of the United States of America, to the the residential and gubernatorial structures in Nuevo Vedado such as the Plaza of the Revolution.
