Märtha Ljungberg visited the amusement park with her family after challenging her four grandchildren to treat her to a daredevil day out.
Photos of the outing posted on Facebook by the Liseberg park earlier this week quickly scored hundreds of likes, with Swedish media soon picking up the story and sharing the snaps of Märtha pictured smiling on a number of scary rollercoasters.
One of Märtha’s grandchildren, 21-year-old Emil, told The Local the pensioner had had a brilliant time, having previously visited the park in the 1960s.
“She was excited to return and thought it looked pretty different this time round compared to when she was here 50 years ago,” he said.
As well as Märtha’s grandchildren, her son, daughter-in-law and great grandchild joined the senior citizen at Liseberg and according to Emil they are all thrilled that their cool relative has become something of a national celebrity this week.
“I don’t know where to start, at first I wasn’t sure she knew what she was in for,” Emil said.
“But she outdid all of us and she took everything with ease.”

He added that Märtha herself still doesn't seem to understand what all the fuss is about, and said that the family had enjoyed the media attention.
“People write all kinds of enthusiastic posts, with most of them saying how fun it is to see her good spirits even at this age,” said Emil.
He revealed that Märtha’s favourite was the rollercoaster Helix, the fastest of its kind in Scandinavia and said to mimic the feeling of taking part in a 100km per hour drag race.
Liseberg, located in central Gothenburg, opened in 1923 and is the biggest amusement park in the Nordic region.
Märtha Ljungberg is set to celebrate her 89th birthday next week, making her just three years younger than the park.
