I assume this stunning shot was made during the 1915-1916 Panama Pacific Exposition.  I grew up calling it The Arboretum.

The largest outdoor lath structure in the world underwent a $28 million renovation, reopening to the public in December 2024.

I love this twilight shot.  I can't tell if it was taken before or after the reconstruction.
