Overlooking – and largely overlooked by – traffic on Kildare Street, what’s currently called the Department of Business, Enterprise and Innovation (but was originally the Department of Industry and Commerce) is like a little bit of the Rockefeller Center in Dublin. The building was designed in 1935 by James Boyd Barrett and is constructed of granite with a wonderful five-storey arched window over the entrance, its glazing bars in steel. The limestone relief over the door might be described as Hiberno-Deco, since it depicts Lugh, the Celtic God of Light, animating a fleet of aeroplanes. It was the work of Cork-born sculptor Gabriel Hayes, who was also responsible for another panel on the side elevation (School House Lane East) showing muscular construction workers engaged in various tasks.
