Over 100 people attended the 50th anniversary celebration marking the naming of the revitalised Mrs York's Garden on Saturday May 12.
The event highlighted the remarkable work carried out by the late Bertha York who, in 1963, started the painstaking planting out of the site overlooking Town Beach.
Paul Midson recalled his grandmother as a remarkable and resilient woman who set about the work against all expectations.
"People really didn't know who they were dealing with," he said. "She was a resourceful woman and created this remarkable place."
Mr Midson was joined by several members of the York family at the celebration, including Beth Midson, Melissa and Andrew Darnley, Megan Carter and Glenys, Deja and Lance Pearson.
Friends of Mrs York's Garden spokesperson Di Davison said she hoped the current work carried on the tradition of Mrs York's work.
"We are trying to follow the essence of the work she started," Mrs Davison said.
"Our aim is to create a place where people can find solace; where they can take time for themselves.
"This is a beautiful place and we have followed Bertha's ideas and ideals."
Port Macquarie-Hastings Council mayor Peta Pinson announced during the celebration that council will install a state-of-the-art water fountain in an appropriate place within the gardens.
"Congratulations to everyone involved in this project," she said.
The celebrations included, the official opening of the newly-constructed steps from Stewart Street to the garden - which cost some $17,000; Mrs York's walk which links the gardens to Allman Hill; the Maritime Museum Slipways' ship signage; and, Mrs York's walk which extends through the gardens.
Bertha York started her work on the garden in 1963 as a labour of love. She wanted to tidy up and beautify the space that was dear to her heart.
Five years later, the area was officially named Mrs York's Garden.
Although the area was not maintained for several years after her passing, in 2015 a group of volunteers - the Friends of Mrs York's Garden - banded together to reinvigorate the area.
Member for Port Macquarie Leslie Williams was also a guest, Uncle Bill provide the Welcome to Country while a local Aboriginal group provided three dances.
