Entail and chapel foundation deed by Gonçalo Eanes de Pamplona, citizen of Porto. The monastery of S. Francisco do Porto granted Gonçalo the possession of a chapel in the church of the said monastery, dedicated to S. António, in which Gonçalo had the right to bury himself and his descendants. Gonçalo Eanes de Pamplona accepted the chapel and decided to establish an entail for the service of God and for the salvation of his soul and that of his deceased wife, Leonor Gomes de Miranda. To this end, he entailed urban and rural properties in Porto and in the "termo" of this city and of Barcelos. The estates were united in the "Morgado" and its administrator had to pay annually the fees for the perpetual masses to be celebrated in the chapel of S. António, as well as 2,000 reis to be spent on the chapel's "fábrica". The founder would be the first administrator, and he would later choose one of his children as his successor. If he failed to appoint the next administrator, the succession would pass to the first-born son or, alternatively, the first-born daughter.

Followed by the letter of possession of the chapel (1533-07-30, fl. 141).
