Students haven't gone through these doors in a long time. If I had to guess, the school probably closed in the late 80s or early 90s and was replaced by Ridgewood Public School. Unlike Norland Public School, this building was allowed to rot.
Chicken wire protects the windows from vandals. This location is fairly lucky in that it hasn't been horribly vandalized - it's right in the middle of a residential area, so there are too many eyes. Nobody asked what I was doing when I was wandering, though.
