Montevideo
Of much greater importance is the division of the city into 62 barrios: neighbourhoods or wards. Many of the city's barrios--such as Sayago, Ituzaingo 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 Paris. Each barrio has its own identity, geographic location and socio-cultural activities. A neighbourhood 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.
