Palau de la Musica Catalana

This gem located in the heart of Las Ramblas should be a must see on your list.  The music hall is known for it’s beautiful ornate stained glass ceiling and mosaic work throughout the building.

You can only see the inside by going on a guided tour.  They sell out quickly so you should buy your ticket in advance (a day or 2 before is plenty).  The last tour is at 3:30 daily.  Try to see what is playing on their website and see a show there.  Apparently the lighting and acoustics are quite dazzling.  I wish we had thought to find out in advance what was playing.  After having seen it on the tour during the day, I was very disappointed to have missed seeing a performance at night.  They have everything from flamenco to opera and classical music concerts.  They even have pop concerts there as well.  www.palaumusica.org
