Almost all historical buildings have inspiration in the molding and tile work. Many quilters have created showstopping quilts based on stained glass windows, architecture, mosaics and tiles in cathedrals, art museums or buildings built prior to 1930 (especially ones that were intended for public access).
Some stunning examples are Judy Matheison's Bristol Stars quilt based on the floor tiles of the Bristol Cathedral in the UK

and Nora McMeeking's Bella Bella quilts inspired by Italian mosaics

Some very talented quilters here on the QB have posted pictures of their renditions of quilts based on Frank Lloyd Wright stained glass

I have taken inspiration from the frames from Hudson River School paintings in the museum. I saw some great tile work in the restrooms at Hoover dam (very art deco!) and the molding, parquet wood flooring and trim work at a local mansion built pre civil war really got my creative juices flowing as well as Victorian wrought iron fences.
Inspiration for quilts and quilting motifs are all around us. Good for you that you noticed and took a picture. I hope you make something great and share it with us.
