When I was doing initial research for the MusicTown identity I stumbled across this 2009 documentary about the history and design of Liberty Hall. As usual with buildings that I see every day (it's the first thing I see when I get out at Tara Street station on the way to work) I knew very little about it, but this 24-minute short gives a good primer in how the original intent for the structure has been eroded through a combination of neglect and thoughtlessness. The interview sections with architect Desmond Rea O'Kelly are particularly fascinating.
