I found the pictures below at the Library of Congress web site. They were taken in 1978, and apparently someone decided to record the buildings for posterity. It's a shame they didn't think to take pictures before they removed the animals - these photos are spooky to me. I remember the buildings, but only just. The last time my parents brought me to the zoo was probably 1965. In light of today's zoo practices, these buildings seem positively primitive. They were old and run down when I saw them, but the animals were no less grand for their surroundings. For those who wince at the tiny, bare quarters the animals were held in, a story. My father told me that when he was at the zoo once - probably pre-war - he watched an elderly woman approach the lion cage at the outside corner of the building. The cat, a big male, looked at the lady, lifted his leg, and sent a stream of piss directly towards her head. No doubt, the old lady took one for our sins, bless her soul.
I wonder what happened to the head that projected from the building above the front door of the elephant house. Did they just destroy it? It was modeled on one of the three original elephants who opened the zoo. There must be someone who knows the answer to this.
