The Lluís Millet hall is a salon located on the second floor of the Palau that is named after one of the founders of the Orfeó Català. The hall is a popular gathering place for concert-goers and also serves as a teaching area for visitors touring the building. From floor to ceiling the hall is two stories high and affords views of the intricate mosaics on the two rows of columns outside its windows that are much better than those available from the street.
