Some older American colleges and universities have a springtime Ivy Day tradition that, among other activities, involves placing a stone plaque on a building and perhaps planting ivy nearby. They were doing that at Penn when I was there, though as a grad student I wasn't involved. Penn still has its Ivy Day, but I don't know if any ivy is still planted.
Ivy is not physically kind to building exteriors and camouflages a building's architecture. It's my impression that actual ivy is disappearing from Ivy League buildings and elsewhere: correct me if I'm wrong.
One example of disappearing ivy is the famous Empress Hotel in Victoria, British Columbia, Canada. Once upon a time it was covered with ivy, and now it has none.

The Empress as seen from a ship in the mid-1920s. The dark areas are ivy.
A view from the 1940s. The hotel got its final major enlargement in 1928 and much of that part is ivy-covered.
A July, 1948 photo with, in the background, the north side of the hotel (at the left in the previous image) covered with ivy.
A photo of the Empress I took in 2013. The north (left) part of the hotel is now ivy-free, but plenty remains on the original section.
A photo I took recently, following the hotel's latest renovation. There's no ivy to be seen. A big improvement, in my opinion.
