“Massimo Bartolini’s impressive green outdoor library titled Bookyard was constructed by the artist in the idyllic vineyard of St. Peter’s Abbey in the Belgian town of Ghent. It is part of the Track art festival, and visitors are invited to take a book along in exchange for a small donation.” The first image and quote were taken from here : The Art of Reading by Kay Kremerskothen.

Shame about the fact that rain and snow usually do not go well together with books. This would be my idea of paradise, a library in the middle of an orchard.
