Investigation Summary
The ruined Quinta de Santo António da Juncosa, in Rio de Moinhos, Penafiel, is tied to the legend of the Barão das Lajes, who is said to have dragged his wife to her death by horse out of jealousy and to haunt the estate with her. The tale appears in print as early as 1912 but is unsubstantiated and dismissed by some as fabrication. Recorded by PRN as a reported/folkloric case — historical context, not proof.
