When Constance arrived to marry Pedro she brought with her Inez de Castro as Lady in Waiting. Inez and Pedro immediately fell in love. It was a love that would last through death.
Pedro's father did what he could to keep the lovers apart but Pedro set Inez up in a castle of her own where they had four children.
When Princess Constance died in childbirth in 1345, Pedro wanted to make Inez his queen. Alfonso had other plans and intended to arrange another political marriage for Pedro. He banished Inez to Spain and when Pedro still found a way to meet her privately in a secret hideaway, he ordered three men to find her and kill her. They waited one morning in 1355 until Pedro and Inez said farewell at the spot later named Fountain of Tears and Pedro set off hunting. Then they attacked her and murdered her in front of her young child.
Pedro was heartbroken and enraged. When he became king, he tracked down two of the men who had murdered Inez and had them executed ripping out their hearts as he said they had destroyed his.. He told his court that he and Inez had been secretly married and as such she was entitled to be his Queen. He ordered her body exhumed and according to stories had her set on a throne beside him with a crown on her head. His courtiers were told to kiss her hand to declare their loyalty to her as their Queen.
She was reburied at the Monastery of Alcobaca and Pedro had an ornate marble coffin constructed for her. Scenes from their lives were inscribed along with verses and quotations on the coffin. Eventually Pedro was laid to rest beside her. His orders were for their coffins to be set in such a way that when they rose from their graves, they would be face to face.
The Fountain of Tears above, where Pedro and Inez said their last farewells, is a still existing attraction for those with a romantic soul.
