3. Stained Glass Has A Rich History In my video about why Stained Glass is such an inspiring art, I invite you to be mindful of the beautiful glass around you. My students are excited to tell be about all the windows they have noticed during the week because they are paying closer attention. Stained glass has been around for hundreds of years in Cathedrals, castles, government buildings and lots of residences. It's about time for you to have some too.
