A Book of Condolences has opened at Cork's City Hall for Sinéad O'Connor and will remain open for a fortnight.
The City's Lord Mayor Cllr Kieran McCarthy said:
"I feel it is an end of an era today. I think, not only was Sinéad's voice stunning and her lyrics thought provoking, she has led a revolution in the importance of speaking up and speaking out about activism, trauma, mental health, spiritualism and she has changed people's lives, so Sinéad rest in peace".
Sinead O'Connor, who died yesterday aged 56, was found unresponsive at her home in London.
Police in the UK say her death is not being treated as suspicious, and she was pronounced dead at the scene.
She has been described as a "force of nature" and an "immensely talented" singer-songwriter.
Sinead O’Connor has been described as the “voice of a generation” amid tributes from around the world following the 56-year-olds death yesterday.
Phil Coulter, who produced her 1994 album Universal Mother said she had a voice like no other:
"People forget why Sinead O'Connor became famous in the first place, which was her voice - a glorious God-given voice. I've been fortunate in my career in the studio to work with major, major talent, wonderful voices, but Sinead was really was exceptional. One of the greatest voices this country has ever produced without any shadow of doubt".
Today flowers and candles are being placed outside Sinead O'Connor's former home in Bray County Wicklow.
In January 1992 ‘Nothing Compares to you” made Sinead O Connor a global superstar.
But despite her fame, she didn’t shy away from controversy, in the same year she was thrust into the global spotlight, she ripped up a picture of the Pope on one of the Americas biggest TV shows Saturday Night Live.
