Bishop Lucey Park will close next Tuesday for two weeks in order to facilitate advance works on its redevelopment.
The City Council say the redeveloped park will be a key element of the regeneration of the Grand Parade Quarter.
The redevelopment will include improved access to the historic city wall, a new pavilion and plaza for events along with a new tower to mark the eastern entrance.
The advance works will include the removal of a limited number of trees and pruning of others to offer more sunlight to people enjoying the park and to support the works.
