The complete Manueline motifs, including gargoyles, gothic pinnacles, statues and "ropes".

The so-called Window of the Chapter House (Janela do Capítulo), a huge window visible from the Saint Barbara Cloister in the Western façade of the nave, carries most of the typical Manueline motifs: the symbols of the Order of Christ and of Manuel I, and a fantastic and unprecedented elaborations of ropes, corals and vegetal motifs. A human figure in the bottom of the window probably represents the designer, Diogo de Arruda. This window of the Convent constitutes one of the masterworks of Manueline decoration.
