A lot of churches have stained glass windows, but the ones in this church in Ikitsuki, Japan, were made from the wings of over 30,000 butterflies.
Brendan Eagan explains:
The priest who helped build and run the parish had a passion for butterflies and his practices as a Lepidopterist allowed for this breathtaking art to be made.
