Quick link to footage posted up on youtube…. (see link below).
Famously, this is where the 1969 IRA split was articulated. Jimmy Steele gave a well-known speech at it (reproduced in various histories of the IRA). Ironically, the commentary on events that day is largely from those who ended on the other side of the split. In reality, the split dates back to 1939 when the IRA formed a Northern Command. Even afterwards, the Officials referred to a ‘Provisional Alliance’ reflecting the presence of multiple factions rather than two sides. The blurry podium footage seems to be from just before Jimmy’s speech.
