The Marble Arch Mound, which was supposed to attract people back into the heart of the city, charged visitors up to ￡8 when it opened in July.
However, the ￡6m artificial hill was forced to close temporarily when plants and grass began to die on the structure surrounded by scaffolding.
Scheduled to run until January, it shuts for the final time on Sunday.
