My grandmother often spoke about the Theatre Royal and used to struggle to explain how big it was - "Was it much bigger than the Olympia?!"
EDIT:
Often commented that a venue this size doesn't exist in Dublin now - about the mark of Hammersmith Odeon / Apollo
It was apparently the biggest capacity theatre in these islands in its day. What's fucked up is that as beautiful as the 1935 building undeniably was, its predecessor was another gem we'd be proud to have in our city today.
