Acclaimed sculptor Antony Gormley has defended criticisms of his latest installation featuring life-size human statues on top of university buildings.
Some students at the University of East Anglia (UEA) in Norwich claimed the figures resemble people contemplating jumping off.
But Gormley said all art should be "unsettling" and his work was "nothing to do with suicide".
The work is part of a sculpture park being created on the campus.
One student said: "I really did think it was someone who was going to jump off a building."
Gormley is one the UK's leading artists and is probably best known for his Angel of the North.
In defending the UEA installation, he said: "These works are nothing to do with suicide, they're actually to do with life and they're placed on the skyline in a way to make us think about space and distance.
"Universities are places where people spend a lot of time thinking about the thoughts of others,
"I think it's a wonderful place to balance that intellectual life with an object that is silent, it doesn't need to be read. It has to be felt, it has to be lived with," he added.
Calvin Winner of the Sainsbury Centre for Visual Arts, which created the art trail, told the BBC: "Part of campus life is about debate and I would have been disappointed if there had been none."
Normally shown in cities, Gormley said he chose to display the work at the UEA because of its Brutalist concrete architecture in natural surroundings.
"It shows how human made things can co-exist with the elemental world," he added.
The sculptures will remain at the UEA for five years.
