Building codes were laxer in the 16th century and gaping holes to a lower floor were allowed. No information is available as to perhaps this was a heating duct hole or contained a fireman's pole for easy downward access to the basement. Modern Portuguese have placed a grate over the hole to preserve the lighting possibilities without completely removing the possibility of a twisted ankle.
