Everyone knows what Hill 16 is but how many know the rich history and magic that occurs there on a matchday when the fans bring this dormant volcano in Dublin's Northside to life? The terrace at the Railway end of the playing field was constructed in the 1930s with rubble from the Easter Rising and given its new name. This documentary illustrates the rich history and unique connection Dublin GAA fans have with Hill 16 and how that bond began.
