In the circa 1900 photo above, men lounge in what is identified on the back as "the rotunda" at the Hotel Green.
I did a somewhat comprehensive post about the Hotel Green on my Pasadena PIO blog last year. You can see that post here for plenty of background.
A couple of photos that weren't included in that post:
The Moorish Room circa 1900 in the portion of the hotel that is now known as the Castle Green...

And of course here's the Castle Green today as seen from across the street.
Many thanks to the Pasadena Museum of History for the black-and-white photos above and the Castle Green for the color photos.
My retirement bash in March was in the salon, sunroom, Moorish room, Turkish room and ballroom at the Castle Green and it was a wonderful affair! See some photos here (click on each photos for a description).
