In relation to the Matrena bridge, the tombstone mentioned by Amorim Rosa, which would be at the entrance to it saying: "Nicolau Pina made. Year 1706" (currently considered missing).
Both facts make sense: that it was a Pina, the family that owned Quinta da Matrena, who ordered the bridge to be built; as well as the date of its construction, since there are no known previous documents that refer to this crossing.
Only the archaeologist Salete da Ponte, in the article "Achegas para a carta arqueológica - Tomar", published in the magazine "Portugália", new series, volume XVI, in 1995, refers to it as a Roman bridge.
