Here are high resolution versions of the 5 ceiling tiles in the Norman Hall at the Grand Lodge of Pennsylvania in Philadelphia.
The ceiling features 25 different tiles, in a 5 x 5 grid. There are 5 different designs.
I took these photos myself after being granted access to photograph the room for almost an hour in 2009. The Freemasons were very kind to allow me to do this.
Entering the Norman Hall
Some of the repainting and restoration work has been destroying the original meaning and subtle detail in the designs, however these ones seem good to me.
Like Coral Castle, the entrance to the Norman Hall is on the West side.
