Having heard that we should see this galleria, we stopped in one evening to check it out, and came back again during the day. Built in the 1890s, it is impressive....long halls, huge glass dome, beautiful mosaic floor, stunning details from floor to ceiling. It was built as a public space for shopping, restaurants, businesses, with some residential above. On both visits, there were lots of people inside, mostly milling about, eating at the restaurants. As a historic space, it's worth checking out.
