Estácio de Sá, the city's founder and nephew of Mem de Sá, ended up losing his life in the attack on the French in 1567, in the Batalha de Uruçumirim, where the Outeiro da Glória is located today. Shortly after the battle, Mem de Sá decided to transfer the seat of the new city to the top of Morro de São Januário – which later came to be called Morro do Descanso and was finally renamed Morro do Castelo – for security reasons and also following the Lusitanian tradition of occupying elevated sites for the founding of cities.

From up there, the inhabitants could have greater control over Guanabara Bay. And there the Jesuit College, the Main Church (Sé) and the Church of Santo Inácio were built, along with the fortifications needed for the city's defense, the Municipal Chamber, and the warehouses of the Royal Treasury. The buildings followed the experiences of the colonizers who, drawing on Roman, Visigothic, Christian, Arab, and Renaissance influences – peoples who had coexisted in the Iberian Peninsula – stamped the Portuguese building pattern onto the emerging city. These diverse experiences fed the idea of a city always in motion, geared toward the future, an ideal city that existed beyond its physical form.

Perched on top, the city of São Sebastião do Rio de Janeiro dominated the landscape. From there, one could observe the contours of the mountains and the calm waters around. The men and women who inhabited that hill gave meaning to the new. The mud-and-wattle houses were rehearsals for dreams of the future.
