niagara falls, courtyard, clock chimes, near sheraton???

I need to find out what the courtyard/garden/little park area is right out front of the Sheraton Fallsview Hotel on the Canadian side of Niagara Falls. It has a big theatre looking courtyard with a small little area with a garden of trees and a small pond. Does anyone know what this is called and if there is a place that has photos of it?

Also, we heard last February at night, around 11 PM, what seemed to be some sort of chimes going off playing a song. I am guess it was coming from some public clock and it probably plays every hour. Does anyone know what the song is that it plays or where to find out what it is?

Thank you!

Michael
