The main branch of the Ottawa Library features this stained glass window, lit from behind by lights as opposed to daylight (there's a hallway beyond that wall). I'll experiment with more takes on this one periodically. As opposed to the church stained glass windows with religious themes, this one has a literary theme, with authors like Shakespeare, Dickens, Tennyson, and Scott represented.
Below is open space surrounded by staircases and balconies for the second and third floors; the floor is ideal for author readings or performance space. While I was there, a quartet of musicians were putting on a performance. Here three of them were playing classical music.
