The last nine houses of the Virtudes Promenade (no. 28 to 53 – a count that refers to eight dwellings only, as the first has no entrance facing the Promenade and, therefore, no number) were directly connected with the Dr. Barbosa de Castro Street. Here, the first floor, facing the Virtudes Promenade, corresponds to the ground floor of the other street. Given the difference in height, it is plausible that the relation between the façades of both streets underwent changes as the Promenade was created.
