Modern Havana is a region of Havana Cuba, wich begins in Vedado, northwest of the Old Town. 23rd Street, is the city´s main axis, also known as "La Rampa" (the Ramp) because of the gradual rising of its lower section. Luxury hotels like the National and the Habana Libre line this street, a remarkable legacy of years gone-by. The neighboring streets teem with Art-Nouveau houses and villas. The political center lies at Revolution Square and its surrounding buildings. Close by, Columbus Cemetery expands on itself, today a National Monument and a genuine marble city for the deceased, dating back from the late 19th century. Further ahead, the aristocratic section of Miramar joins the landscape, with palace-like villas which have been turned into embassies, expensive restaurants and exclusive stores.
