We lived in downtown Harrisburg, Pennsyvania for a few years, right next to the State Capitol building. It's reported that in 1906 President Roosevelt claimed this building as "the handsomest building" he'd ever seen. The art and architecture that make up the Capitol building are awe-inspiring.
One of the very prettiest elements in the building is the ceiling of the Supreme Court chambers. The grand stained glass dome window in the center of the ceiling catches my breath.
This tam design is inspired by that incredibly beautiful historical architecture.
