YIKES! THAT IS QUITE THE COLLECTION OF OWLAGE TO ADD TO MY COLLECTION!!!
Thanks for the pix!
You might check out Rice University - their nickname is the Owls. Also the infamous University of Texas tower. It was designed by a Rice architect and includes owl faces when viewed from oblique angles, as in the Big Ben photo you posted. Moreover, there is a miniature Texas Tower on the Rice campus. Apparently a scale model from before the tower was built, I don’t know.
