This paper investigates the principles that guided the design of the Vila Militar of Rio de Janeiro, a military town built in 1908. It is a narrative about the urban and architectural features of the pioneering military town in Brazil. Fruit of a Brazilian Army modernization program of the early twentieth century, this village was planned as the first autonomous unit, consisting of bureaucratic and residential buildings, military schools and training areas, in order to serve as a model to other military town to be built throughout the country, according to Frank McCann (2007). Designed in accordance with modern principles of circulation, hygiene, large green areas, zoning, standardization and easy reproducibility of forms, the blueprints reflected the corporate hierarchy in space and on the houses’ architecture. It means that, each rank was settled in different areas and with different types of housing but also different typologies was designed for the same rank offering a rich architectural landscape. In addition to the institution´s modernization, this settlement had a pedagogic function in introducing new notions of space and habitability and, moreover, it had a symbolic role of representing the officer’s emergence in the sociopolitical context of the First Republic. The officer´s houses in the Vila Militar breaks with the previous types of military housing from the 19th century. Although it was not effectively reproduced in other places as firstly intended, the construction of the Vila Militar still ensures its significance as a pioneering military living in the 20th century and due to its role as one of the main establishments of the corporation in Brazil. It is part of a building type with a striking presence in Brazilian cities landscapes along the 20th century. Finally, this paper strives to contribute with one more chapter of the history of Brazilian´s military town and, consequently, Brazilian´s history of urban and housing planning
