The two side buildings flanking the Seminário were built in the late 1800s, and are almost Palladian in their configuration. Surely someone was looking at the Quattro Libri when detailing the Doric portico; not so much for the windows and balusters, which still refer to the main, older building. The proportions are serene and Classical and note how the imposts at the ground floor arched windows match the ones at the main door.
Easily enough, they were called Casa Nova and Casa Novíssima (the “New House” and the “Newer”) according to the order of construction, and so the central received the moniker Casa Velha, “Old House”.
