Conradh na Gaeilge
No. 6 is a building with many historical connections including as headquarters of Arthur Griffith's Sinn Féin. It was donated by the state to Conradh na Gaeilge in 1966 on the fiftieth anniversary of the Easter Rising. This was to mark the contribution of Conradh na Gaeilge to the nationalist movement, six of the seven signatories of the 1916 Proclamation having been members of the Conradh. The building was the subject of a documentary "Uimhir 6".
