Casas del Tratado de Tordesillas, Historical monument in Tordesillas, Spain.
The Casas del Tratado de Tordesillas are two adjoining palace buildings in the Castilian town of Tordesillas, Spain. The older one dates from the 15th century and is built with dressed stone at ground level and brick on the upper floors, while the newer one was added two centuries later.
In 1494, the older of the two palaces hosted the negotiations that led to the Treaty of Tordesillas, an agreement between Spain and Portugal dividing newly discovered territories between them. The treaty shaped the course of colonization across the Americas and Africa for generations.
The entrance still displays the royal crests of the Catholic Monarchs alongside the heraldic symbols of local noble families. These carved emblems give a sense of the social standing that once defined life in this building.
The building now houses a museum dedicated to the Treaty of Tordesillas and the geographical discoveries of the 15th century. Both palace sections are connected inside, so a single visit covers the full complex without needing to go back outside.
The 1994 restoration was timed to mark exactly 500 years since the treaty was signed, turning the building itself into part of the commemoration. Standing inside, you can clearly see where the 15th-century stonework ends and the 17th-century brickwork begins.
