They came in their hundreds to pay their respects.

Family, friends and colleagues of Anthony Fatayi-Williams, who died in the London bombings on 7 July, were united in grief at his funeral on Saturday.
Some had made the short journey across London, others had travelled from as far away as Nigeria to attend the funeral at Westminster Cathedral.
Every race, creed and colour were represented at the service.
Some dressed casually, others wore black mourning suits, more still were swathed in the bright colours of traditional Nigerian dress.
It was time for all them to say a final goodbye to the "peace-loving" 26-year-old who was one of 13 people killed in the Tavistock Square bus blast.
The mourners were led by Anthony's father Dr Alan Adebayo Fatayi-Williams, his mother Marie, and his two sisters, Lauretta, 16, and Aisha, 13.
In a written tribute, Aisha said: "You will always be my darling brother."
Bishop Alan Hopes, who led the service, talked about the "terrible tragedy" of Anthony's death and said terrorism was making everyone pay "a price too enormous to calculate".
Those who paid personal tributes during the service included his parents, his uncle, cousin, best friend and boss from Amec, where Anthony worked as an oil executive.
His uncle, Tom Ikimi, former foreign affairs minister in Nigeria, described Anthony as a "world citizen" who was proud of his Nigerian and British heritage.

He said London-born Anthony - who had a Muslim father, Catholic mother and white grandmother - was educated in Nigeria, Paris and the UK.
Speaking at the service he said: "I can see Nigerians, people from different backgrounds, white and black, I can see people of all ages gathered here representing the different races of humankind.
"Anthony was a world citizen. He broke the boundaries of race and broke the boundaries of religion and was looking at a great life ahead.
"But all of his hopes and aspirations were truncated by the events of 7/7."
Mrs Fatayi-Williams, who travelled to the UK after the bombings to search for her only son, said she would "cherish" his memory.
She told the congregation how she and her son would talk to each other in French when they wanted to speak privately.
And in one of the most moving moments of the two-hour ceremony, she spoke a few words then sang a tribute to her son in French.
Dr Fatayi-Williams joined his wife to launch the Anthony Fatayi-Williams Foundation for Peace and Conflict Resolution in his memory.
He said: "We, Anthony's parents, have resolved to lend ourselves and our voice to finding peaceful ways to overcome violence and terror.
"Violence in whatever form is not the solution to the issues of differences between peoples and civilisations.
"Violence only begets more violence, more hatred and more pain and indeed
more suffering. Enough is enough."
Music during the mass included hymns sung by Westminster Cathedral Choir and an African offertory procession song by family friend Julie Coker.
Some read poems while others offered their personal memories.

Tom Ikimi Jnr, 26, spoke of his love for his cousin, who was born just two months before him.
"Anthony was a person who didn't handle sadness very well and always tried to extract the tiniest bit of joy out of everything," he said.
"Tears and sadness don't do anything for Anthony at this point. Only joy and happiness is the way he should be remembered."
Anthony's boss at Amec, Peter Madden, read out tributes from a book of condolence they had opened for colleagues.
One read: "Ray of sunshine would be an understatement to describe you."
A second said: "Anthony will be sadly missed, but remembered always with a nudge, a wink and a smile."
After the ceremony, Anthony's coffin was transported in a cream Daimler hearse to Hendon cemetery in north-west London for burial.
A simultaneous memorial mass was also held at the Church of the Assumption, in Falomo, Ikoyi, Lagos, Nigeria.
