Crann an Óir (Tree of Gold) was commissioned by the Central Bank of Ireland to mark Dublin's year as European City of Culture in 1991. The work is comprised of a formalised tree in gilded bronze surrounded by a sectioned building in Wicklow granite.  The tree symbolises growth under careful management and the building the role of the Central Bank in protecting and husbanding the wealth of the country.  The open nature of the architectural element in the design suggests that this wealth is not locked and hidden but is shared by the public.

A public exhibition of the 20 shortlisted artists' proposals was held for over a month at the Central Bank before the Bank selected O'Doherty. The then Taoiseach, Charles J Haughey, officially unveiled the sculpture on 30th November 1991.

Éamonn O'Doherty (1939-2011) was a sculptor, printmaker, photographer and architect born in Derry.  He received several prestigious commissions for public spaces in Ireland and abroad including  'Crann an Óir' at the Central Bank, Dublin; the James Connolly Memorial, Beresford Place, Dublin; the Great Hunger Memorial in Westchester County, New York; the Emigrants Sculpture, Waterloo Place, Derry; and the 'Protogonos' sculpture at St. James's Hospital, Dublin.

O'Doherty was for many years a lecturer in architecture at the Dublin Institute of Technology, Bolton Street. He also taught at the University of Jordan, the Univeristy of Nebraska, and the École Speciale d'Architecture, Paris. In 2002, he gave up teaching to concentrate on artwork, specifically on small-scale, more personal work.
