In the seventeenth century a group of Benedictine monks formed in the region, donated by a farmer, the Monastery of Saint Benedict and the Tijucuçu Farm, used by the monks to raise cattle. In 1717, the monks began to erect the chapel dedicated to Saint Cajetan di Thiène (In Portuguese, "São Caetano"), the patron saint of bread and work, in the place where the Old Matrix of St. Caetano is today. They passed the farm to be called Farm of São Caetano do Tijucuçu, then São Caetano Farm. Around the farm was developed the district of São Caetano, in the same territory of the city of São Paulo. It was first enumerated in 1765, when the Morgado de Mateus determined that a census of the population of the Captaincy of São Paulo was made. Its inhabitants were farmers and tropeiros and they received the sacraments in the Chapel of São Caetano.
