It was wound up in the summer of 2020, although members dissatisfied with this decision established a successor organisation with similar objectives, the Public Statues and Sculpture Association, in the autumn of the same year.
It campaigned for the listing, preservation, protection and restoration of public monuments and sculpture, covering a period from the Stuart monarchy to the present day.
Later projects included collaboration with other organisations and individuals to oversee production of the Custodians Handbook, published in 2005 and occasionally updated.
[2] In July 2020, the PMSA's chairman, Sir John Lewis, wrote to members to inform them that the decision had been taken to wind up the association, partly for financial reasons, and partly on the grounds that "the handing over of catalogue data to Art UK in 2018 effectively brought the PMSA's twenty-year National Recording Project to a successful conclusion".
Among other activities, the PSSA aims to continue and complete the published county-by-county survey of UK public sculpture begun by the PMSA.
