The Irish flag flies at half mast over Leinster House in honour of Nelson Mandela.
Books of Condolences at City Hall in Limerick and at County Hall in Dooradoyle will open at 2pm.
Mayor Kathleen Leddin described the anti-apartheid politician as “the moral compass that guided an entire nation through dramatic, positive change during the past 20 years.”
She said: "Mr Mandela’s inspirational leadership and unfaltering courage in the face of adversity set an example for the rest of the world to follow. His passing is a loss to the entire international community. However, we should celebrate his achievements as an anti-apartheid icon and as the father of modern South Africa.”
The Books of Condolences in Limerick will remain open until 5pm on Friday, December 13, 2013.
