The New York Times the, that the project was conceived by local artist Manfred Laber, who died in 2018.
Laber proposed to create this project in 1993 - for the 1th anniversary of his city. In 200, he and the city government established the Wemding Time Pyramid Foundation to manage and finance the work after the artist's death.
The pyramid will consist of 120 concrete blocks, which will be added every ten years starting in 1993. In the end, the building will be about seven meters high.
Another, fourth unit was installed last week. One of the city's residents, Karl-Heinz John, a former auto industry executive who attended Saturday's ceremony, said he has attended every block-laying event since 1993.
