Sunday Bloody Sunday in Croke Park. The original Bloody Sunday. in Dublin - Croke Park Posted July 21, 2017 2 hours ago, clarky46 said: There's been lots of killings by both sides both wrong I didn't say there weren't and I'm not taking sides. Not the point I was making. Nothing to do with sides. I'm just surprised they have never made reference to the Croke Park Bloody Sunday while playing Sunday Bloody Sunday there. Even Queen Elizabeth could acknowledge it when she visited Croke Park.
