The wood and corrugated iron house in which prime minister Jan Smuts entertained world leaders is in a state of disrepair and desperately needs funds to restore it.
Jan Smuts House Museum in Irene, Gauteng, has made it onto the Most Endangered Cultural Heritage Sites 2017 list, a campaign initiated by the Heritage Monitoring Project.
According to the project, the private foundation that runs the museum has been finding the task "rather daunting".
"The trustees of the Jan Smuts Foundation face a number of challenges. The house and grounds have never benefited from official patronage. Overall, Smuts House is in a poor state of repair and the valuable library with rare books dating from the 16th century lacks the requisite climate control necessary for the preservation of a priceless collection.
"Most importantly, the museum needs resources to explore ways of making Smuts House relevant to new audiences," the campaign said.
The museum was among more than 35 cultural heritage sites identified when the Heritage Monitoring Project called for the public to nominate sites of concern.
