I've always admired the artistic double doors at the Willits Center for the Arts. The building started out as the Women's Improvement Club, then served as the local jail. A great deal of work has been done to repair and refinish the premises, and they have much more to do. They really scored well with whoever designed the entrance.
Sitting at the gallery desk for an afternoon recently, I got to study the interior left panel of the door, with its inset prisms of glass. I think these are of the sort used in the decks of wooden boats, to cast light into the chambers below.
Here are the full doors from the outside. Just lovely.
