Guayaquil Metropolitan Cathedral A municipal heritage publication describes the neo-Gothic project as authored by architect Paolo Russo for the Sociedad General de Construcciones in 1924, and states that from 1941 to 1958 the construction was under Orús, who designed the façade and carried out interior works while respecting Russo's designs. These accounts support treating the cathedral as a multi-phase work with Orús as a principal later director and designer rather than the sole original author.
El Telégrafo likewise states that it was built in the 1930s by Orús, providing contextual information about the owner and adjacent industrial uses historically associated with the site.
Expreso also identifies Orús as the architect of the building in a feature on Guayaquil's historic “castles”.
Other works Academic discussion of Guayaquil's 1930–1948 architectural production attributes to Orús, among other projects, the Edificio Juan X. Marcos, Casa Gabriel Vilaseca (1936), and Edificio La Frutal (1937), and notes his broader involvement across neo-colonial and picturesque currents after 1936. ==Style and significance==
