Between the 18th and 20th of November 2019, we moved to another city and went to the Porto institutions to consult their archives: we started at the headquarters of Northern Regional Section of the Order of Architects (OASRN) and then to the Faculty of Fine Arts (FBAUP) and the Faculty of Architecture of the University of Porto (FAUP). We thank those who received us so well: in the OA, Dra. Lígia Filipe Sampaio (librarian and archivist) and the architect Cláudia Santos (direction of OASRN); in FBAUP, Dra. Isabel Barroso; and, in FAUP, Dra. Teresa Godinho. We returned to Lisbon with new data, new questions and a lot of desire to continue!
