Today marks exactly one year since Berkeley tragedy
Services will be held in memory of those who died in Berkeley today, one year from the date of the tragedy.
Six students were killed when the fourth floor balcony of an apartment fell 12 metres to the ground below.
The five Irish students who died were all from south Dublin and all 21 - medical students and friends Lorcan Miller and Eimear Walsh; Olivia Burke, who went to school with Eimear; Niccolai Schuster, who was at the same college as Lorcan and Eimear, and his friend from school Eoghan Culligan.
Irish-American Ashley Donohoe, 22, who lived in California and was a cousin of Olivia's, also died.
Another seven sustained serious injuries.
The students were on J1 working visas for the summer and were among 40 people attending a 21st birthday party when the balcony collapsed in the early hours of June 16, 2015.
The US Ambassador to Ireland, Kevin O'Malley, said the six would never be forgotten.
An apple tree has been planted in the grounds of the UE embassy in Ballsbridge, Dublin and a plaque erected in their memory, inscribed with these words from Joyce:
Mr O'Malley said the people of the US extended heartfelt sympathy to the families, friends, and loved ones of the students who lost their lives or were injured.
"As the tree grows strong, we will take comfort in the knowledge that the memory of Ashley, Eimear, Eoghan, Lorcan, Niccolai, and Olivia, will remain with us always," the ambassador said.
"We also hold in our thoughts and prayers the young people who are still recovering from their injuries; that they may continue to heal with the love and support of family and friends here and in the United States.
"The remarkable resilience they have displayed sends a powerful reminder to the world of the friendship between our people and of our capacity to unite in times of adversity. I hope the outpouring of love and support from the American people in the aftermath of this tragedy has provided some comfort and brought us closer together."
No criminal proceedings will be brought over the balcony collapse.
After a nine-month investigation, Nancy O'Malley, District Attorney in Alameda County, near San Francisco, found there was insufficient evidence for a manslaughter case.
Initial examinations of the remnants of the balcony showed rot had set in to heavy wooden beams.
Lawyers representing families affected by the tragedy said they are continuing to pursue lawsuits over the disaster.
