The Chapel of Our Lady of Alcamé was built in 1746 by the 1st Patriarch of Lisbon, D. Tomás de Almeida. Its construction lasted until mid-century. XVIII.
This chapel was probably built - like its counterpart, the Chapel of S. Joseph, situated next to EN10, so that farm workers could attend the mass on holy days, since it was not often possible for them to move to the nearest parish, and simultaneously allowed to accomodate these same people when the floods ravaged abrupt these terrain (Lezírias).
