Within the celebrations of the fifty years of the Institute of Archaeology
from the University of Coimbra, its siege since 1986 – the 16th
century Paço de Sobre a Riba (commonly known as Sub-Ripas) –
impose and deserve once more the revisiting of its spaces and history.
Who was João Vaz (the owner of the new palace and the responsible
for the adaptation of the medieval tower), which was the role of his
successors, especially his son António Vaz, in succeeding aesthetic
updating or at what extent those interventions reflected the Portuguese
domestic architecture evolution are some of the topics explored in the
present paper.
