At the Sharpsteen Museum a few weeks ago, I noticed yellow “diamonds” on the roofs of houses in the diorama of “Calistoga’s yesteryears”. What they meant, no one there could tell me.
My curiosity led me to ask a Napa architectural historian, Stacey de Shazo, who told me it was, as I suspected, purely decorative with no significance to its diamond shape or yellow color.
Stacey shared this link which is a resource for those interested in roofing details and design for historic places.
All photos were taken by me with the permission of the Sharpsteen Museum in Calistoga.
