Hundreds of people continued to gather outside the US embassy in Ballsbridge yesterday to sign the book of condolences, bringing wreaths and bouquets of flowers to pay their respects to the American people.
Flowers, candles, teddy bears, US flags and children's toys, most with personal messages and dedications attached, cover much of the embassy's walls and railings.
People also brought more personal items, including a New York Yankees t-shirt, a NYPD baseball cap, a baseball and a New York car registration plate.
Queues to sign the book started at 7 a.m. and continued throughout the day. Matt and Frankie Gallagher from D·n Laoghaire, accompanied by their daughter Sarah, waited their turn on Elgin Road.
"I'm here to express my solidarity with the Americans," said Sarah Gallagher. "It's a very moving and genuine tribute, and one that expresses the feelings of horror and revulsion we all feel," added her mother.
Nine-year-old Laura Groves, from Phibsboro, brought a picture she drew and a bunch of flowers to add to the thousands of personal tributes that line the footpath.
Her mother, Carmel, said: "It's still so shocking, and it's still so hard to believe."
Many of the bouquets and wreaths were made up of red, white and blue flowers, representing the colours of the US flag. Some of the messages attached were dedicated to individuals, other dedicated to "all American children".
American tourists David and Suny Simon from California were moved by the tributes.
Anxious to get home, the couple and their daughter Elishia were due to fly home last Saturday but have not yet received confirmation of their rearranged travel dates.
"It's been a difficult time, but Ireland was a wonderful place to be during this tragedy. The sympathy and support we Americans have been shown by the Irish people and Government has been overwhelming," said Ms Simon.
Many personal tributes from Americans sit alongside offerings from Irish people. One of the most eye-catching dedications at the embassy is a postcard of the New York skyline featuring the twin towers of the World Trade Centre, accompanied by a handwritten narrative of the affection one "devastated New Yorker" had for the landmark.
