2. Palacio de Santa Cruz
Part of the university is this free attraction that is also loved as much for its beautiful architecture as for what you can see inside.
The 15th-century palace is the rectory of the University of Valladolid, and valuable because it was the first building in Spain to be designed in the renaissance style.
The best part has to be the interior courtyard, which is three-storeys high with exquisitely detailed traceries on the first-floor balustrade.
The building holds the Fundación Jiménez-Arellano Alonso, a museum devoted to African art.
If you see nothing else, take a few minutes to behold the two realistic 13th-century head sculptures from Ife, a civilisation based in what is now Nigeria.
