The urbanization of Rio de Janeiro reached its peak with the Pombaline viceroys in the 18th century. Although the city did not bear the traditional marks of European Baroque, it was present in the new spatial dimension.
The urban landscape of Rio revolved around the plazas, and its streets ended in buildings. The spatial arrangement of churches and public buildings produced an architectural design that made the baroque city seem more illuminated. This constructive strategy was the result of the ideas and techniques of military engineers, architects, and street planners who conceived urban space in the 18th century.
Largo do Carmo, for example, was remodeled to keep pace with the transformations of a Rio de Janeiro that was growing at a dizzying rate. The place where, since 1743, the governors' residence had stood was, from 1763 onward, transformed into the Palácio dos Vice-Reis. The square gained a large plaza paved with stones, a stone-cut quay with stairs and ramps, as well as the fountain built by Mestre Valentim (1789), which replaced the previous one erected by order of governor Gomes Freire in 1747. The monumentality of the area was enhanced by the new façade of the Palácio dos Vice-Reis, the presence of the churches in the background, and the star-shaped paving, which directed the eye toward the center of the plaza, highlighting its grandeur.

The layout of the buildings, the treatment given to the paving, and the furnishings of the urban center were designed to produce a theatricality that would impress those arriving in the city. Largo do Carmo represented a simplified version of the great European squares, with the same visual charm.
Another characteristic of the interventions of the period were the public gardens, responsible for introducing new elements into the urban landscape. The first of these was inaugurated in 1783, from the landfill of the Lagoa do Boqueirão da Ajuda: the Passeio Público. With the enlightened orientation of the Pombaline viceroys, the city gained the presence of social reason and artificiality – baroque elements that enchanted passersby.
