"This is a photo of the Portiuncala in Hanover, Mass. which is the burial site of Cardinal Cushing. Last Saturday was the Feast of Our Lady of Angels, and I decided to make a short pilgrimage to the Portiuncala. This chapel is a true replica of the chapel in the Church of Our Lady of the Angels in Assisi, Italy."
If you have ever observed a bird looking for building materials, then you've noted how fussy they are about what they'll include. The little birds who built the nest I found had a particular preference for cottonwood, dandelion floaters (seeds), straw-like stands and some other fuzzy golden material. It was all intricately woven together with great care.
