The Virtudes Promenade area underwent several changes throughout the centuries. The houses were also subject to several demolitions, modifications and additions. Notwithstanding, they follow an architecture that accommodates and humanizes the landscape, making the city more pleasant and welcoming for those who live there and those who visit.
The types of housing in this area deliver continuity to the characteristically narrow and deep allotments that distinguish the built mass of 19th century Porto. However, they also embody advanced construction techniques, such as high floors and the use of the stone instead of wood, which allowed for larger fronts. Some of the houses in the vicinity of the Virtudes Promenade seem to have been the result of an allotment project, that is, the subdivision of land into lots that were destined to the construction of buildings with similar characteristics. The same façade model is repeated, adding to the visual harmony of this historic urban landscape.
