 This dedication might be in gratitude for the concession made by Felipe II to Fabio Nelli awarding him generosity and nobility title.The current coat of arms, which can see in the center of the pediment split of the palace, corresponds to the grandson of Fabio Nelli, Baltasar de Rivadeneira y Zúñiga.Also it belongs to this character the shield that still exists in the Boecillo village (current Vega de Porras), that was country house, property of the banker.
