Closed to the public at the time of research, the Casa de Cisneros, built in 1537 by the nephew of Cardinal Cisneros, a key adviser to Queen Isabel, is plateresque in inspiration, although it was much restored and altered at the beginning of the 20th century. The main door and window above it are what remains of the Renaissance-era building. It’s now home to the Salón de Tapices (Tapestries Hall), adorned with exquisite 15th-century Flemish tapestries.
