I got the scoop!
The bells have been around for years. Simply for ambiance, nothing else. They were out of commission for a few years, badly in need of funding so they could operate again (yes, from the speaker/horns that you can see from the top of the old engineering building. the speakers go all the way around that part of the building, hence why I can hear it all the way out in lot K on my way back to the village.) We had a big donor who gave us money to fix the bells and have them ringing again.
I think there will be a special ceremony or something Friday to thank the donor for the bells. I love them, I know its a generic ring, but I am Catholic, and I remember hearing them in grade school every hour and half hour... Kind of like your school in Taiwan... we were never late from recess!
Enjoy!
