Beautiful works on display, unfortunately no references or any info on any of the pieces. You just listen to a free guide. Like a ghostly exhibition of unknown sources of work. Sad.... I am sure that every piece has a tremendous history behind it! Very hostile atmosphere unfortunately. Forbidden to take pictures while there are photos on every social media, when I asked to take a photo of a photo from a book on display, they suggested I buy the book. I am a regular visitor, admirer of art but not a professional mosaic lover! When asking any question the answer is as lame as everything else. Of course I wouldn't visit again and wouldn't recommend to any.
