Palacio del Condestable Iranzo

This much altered 15th-century palace now houses the city culture department and a library, but it's worth finding your way to the Salón del Condestable inside to see its colourful original artesonado (latticed wooden ceiling with recessed panels), with an elaborate starburst-like geometric pattern and hanging prisms at its centre – a fine example of Mudéjar artisanry (work done by Muslims living under Christian rule).
