importance is the division of the city into 62 barrios: neighborhoods or wards. Many of the city's barrios—such as Sayago, Ituzaingó and Pocitos—were previously geographically separate settlements, later absorbed by the growth of the city. Others grew up around certain industrial sites, including the salt-curing works of Villa del Cerro and the tanneries in Nuevo París. Each barrio has its own identity, geographic location and socio-cultural activities. A neighborhood of great significance is Ciudad Vieja, that was surrounded by a protective wall until 1829. This area contains most important buildings of the colonial era and early decades of independence.

The building facades in the Old Town reflect the city's extensive European immigration, displaying the influence of old European architecture. Notable government buildings include the Legislative Palace, the City Hall, Estévez Palace and the Executive Tower. The most notable sports stadium is the Estadio Centenario within Parque Batlle.
