I've been interested in this place since I was a child, I pass it when i visit my uncle in Dublin and then I come back home. My gran from rooskey told me that a girl she knew, was killed by a bus after some ball,grad or Disco that the girl attended to. It happened before the ballroom was about to shut down in the 80's or 90's. One day, I was researching it all over the web, I saw it went on fire in 2009 suspicously at 8pm here's the evidence that I found:

and also I saw in a weird website that it was haunted because it was abandoned for so long & people saw a figure walking slowly around it when passing by it.
