Belo Horizonte is the capital of and largest city in the state of Minas Gerais, located in the southeastern region of Brazil. It is the third-largest metropolitan area in the country. Belo Horizonte has a population of over 2.4 million, or almost 5.4 million in the official Metropolitan Area. The region was first settled in the early 18th century, but the city as it is known today was planned and constructed in the 1890s, in order to replace Ouro Preto as the capital of Minas Gerais. The city features a mixture of contemporary and classical buildings, and hosts several modern Brazilian architectural icons, most notably the Pampulha Complex. In planning the city, Aarão Reis and Francisco Bicalho sought inspiration in the urban planning of Washington, D.C. The city has employed notable programs in urban revitalization and food security, for which it has been awarded international accolades.
