It was here that queen Joanna of Castile, while nominally reigning, after being declared insane, was confined in 1506 until her death in 1555.
One of the most important buildings in Tordesillas was its Royal Palace, the temporary seat of the itinerant courts of the Castilian monarchies and especially notable for being the place where Queen Joanna I of Castile stayed for 46 years, after being declared insane in 1506.
[1][2] After the palace of Alfonso XI and Pedro I was converted into a convent of Poor Clares, the Royal Convent of Santa Clara, King Henry III decided to build another palace near the previous one, overlooking the Douro river.
[1][2] It had three gates: the main one, to the south facing the river; another to the west, on San Antolín Street and the third to the north, in front of the Alderete palace.
[1] After the death of Queen Joanna, the building was abandoned and, despite carrying out repairs to prevent its state of ruin, it was demolished in 1773 during the reign of Charles III.
