At the beginning of the 17th century, the ground of Quintana de Mortos was levelled, and the stairway was built to join with the upper level, the Quintana de Vivos. Work was carried out by Xácome Fernández and F. González de Araujo. The area was designed for holding major Baroque celebrations. It includes the Puerta Santa, which only opens on holy years, where pilgrims pass through to achieve the Jubilee. It is surrounded by the cathedral sanctuary, Casa de la Parra, the Monastery of San Paio de Antealtares and Casa da Conga.
