There is a legend that tells a story about its construction, which was the result of revenge for a forbidden love. Supposedly, Corina Kavanagh was in a relationship with one of the children of the famous Anchorena Family, who forced their breakup because Corina was not part of a patrician family. Consequently, a giant building was ordered to block the view of the Anchorena house, which overlooked the Basilica of the Blessed Sacrament, a construction that would be the future sepulcher of the family.
