Portugal's pavilion was not large, but its Manueline Gothic front, drawn from the Jerónimos monastery, Batalha and the Convent of Christ at Tomar, made it one of the most distinctive buildings in the section. Statues of Prince Henry the Navigator and Pedro Álvares Cabral flanked the entrance under a frieze of shields. It was designed by António Couto d'Abreu, with W. C. Coulter of San Francisco as local architect.
The octagonal interior worked like a travel album. Large framed photographs showed the Jerónimos, Pena Castle, Coimbra and Évora, and dioramas of Oporto, Lisbon and Funchal filled the alcoves. There were also lace and needlework. At the dedication on March 5, 1915, a hundred girls in the national red and green attended.
