[1] In 1160, D. Afonso Henriques donated Vila Verde dos Francos to D. Alardo, a French Captain and group of Crusaders, in recognition for their support in conquering Lisbon, Sintra, Almada, Palmela and Alenquer.

[1] Tradition suggests that D. Alardo was responsible for constructing the castle, following the Henriques issuing a Foral (charter).

[1] Much of the landscape was inundated with wild blackberries, necessitating the need to clear the terrain, consolidate masonry and reposition some stones.

At that time, researcher Jorge Peixoto, identified the compact structure as a chapel, dedicated to Sõa Luís.

[1] The building is situated in an isolated rural area, implanted at the top of a small hill of outcrops, near the settlement, surrounded by agricultural fields and vineyards.
