Stained glass window at Harvard House, Stratford-upon-Avon. Photo May 2015.
From the information sign:
This stained glass was uncovered in the early 1900s during restoration works organised by local author Marie Corelli. Dating from between 1400 and 1500, it was probably brought here from another building. It is decorated with images of primroses, columbine, oak or holly leaves, and daffodils.
