Just below the junction of the Ribeira de Arronches and River Caia next to the bridge of Santa Maria,  is a rock  called Pedra da Moura (Moorish rock)

Legend says that the rock is enchanted by a delighted  Moorish princess betrothed by her father to a noble,  though she was in love with a prince that was in the war.

The father charmed her to the stone and every St John´s night the  Princess sits on the rock singing songs dedicated to the prince.

It is said that those who pass that night by the stone will also be enchanted.
