The Trastamara Estate Ruins lie in Caroberta Woods in southern Toussaint, southwest of the Termes Palace Ruins. Once the proud seat of the de Trastamara family, the estate now stands in ruins.

According to the tale behind it, the baron’s daughter Marlene once refused a beggar the traditional small meal, and her cruelty brought a curse down on her. The ruins are the setting of the main quest La Cage au Fou, in which Geralt meets the wight that the curse created.
