Hundreds of volunteer builders gathered in the city centre to make the tower, using 1,000 cardboard bricks.
The People's Tower community art event was created to mark the opening weekend of the annual Norfolk and Norwich Festival.
The tower is 22 metres tall and is designed to look like the St Peter Mancroft Church tower.
It took more than eight hours to complete and was held together by more than eight miles of packing tape.
It was designed by French artist Olivier GrossetÃªte.

The woman, 39, suffered "multiple serious injuries" after plummeting to the ground during a "routine" jump over Salisbury Plain, Wiltshire, on 5 April.
Police said it was miraculous she had survived, after her main chute failed and a reserve only partially opened.
A 35-year-old man was arrested but has since been bailed, police said.
Wiltshire Police began an investigation after being alerted by the parachute club at Netheravon Airfield to concerns over what had happened.
Detectives said they were particularly looking for "slinks" or soft links, used to connect the canopy to the parachute harness, which were "missing".
Det Insp Paul Franklin, said the woman, an experienced parachutist, had "very nearly lost her life".
"This woman would have been dead if her chute hadn't partially opened, this meant her descent was slowed enough for her to survive the fall," he said.
The woman was taken to Southampton General Hospital with "multiple fractures throughout her body" and was now recovering at home, police said.
A church made of cardboard boxes has been built in Norwich.
