Denver, the capital of Colorado, is an American metropolis dating to the Old West era. Larimer Square, the city’s oldest block, features landmark 19th-century buildings. Museums include the Denver Art Museum, an ultramodern complex known for its collection of indigenous works, and the mansion of famed Titanic survivor Molly Brown. Denver is also a jumping-off point for ski resorts in the nearby Rocky Mountains. As of January 2013, the City and County of Denver defined 78 official neighborhoods that the city and community groups use for planning and administration. Although the city's delineation of the neighborhood boundaries is somewhat arbitrary, it corresponds roughly to the definitions used by residents. These "neighborhoods" should not be confused with cities or suburbs, which may be separate entities within the metro area.The character of the neighborhoods varies significantly from one to another and includes everything from large skyscrapers to houses from the late 19th century to modern, suburban-style developments. Generally, the neighborhoods closest to the city center are denser, older, and contain more brick building material. Many neighborhoods away from the city center were developed after World War II, and are built with more modern materials and style. Some of the neighborhoods even farther from the city center, or recently redeveloped parcels anywhere in the city, have either very suburban characteristics or are new urbanist developments that attempt to recreate the feel of older neighborhoods.
