The name comes from the fact that the farm belonged to Luís Gomes Mata, "Correio-Mor" (chief of the post delivery) at the time of Filipe II. Built in the 18th century, the palace might have been designed by the Italian António Canevari, one of the architects of the Convent of Mafra. It is preceded by an emblazoned door leading to the patio. Inside, the tiles and stucco ceilings with paintings by José da Costa Negreiros stand out. In the gardens, the waterfalls and tiles with mythological scenes stand out.
