The work of architect Diogo de Arruda between 1510 and 1513, this is the most striking example of the Manueline style anywhere in Portugal. From the roots of a cork-oak, supported by the bust of a captain, springs forth a twisting decoration that climbs up to the left and right in a riot of foliate and marine detail. Crowning it all are the emblems of Manuel I and the Cross of the Order of Christ. Other decorative motifs represent orders of chivalry.
