* The base layer, measuring {{convert|13.8|by|13.8|m|ft|abbr=on}}, will consist of 64 blocks arranged in 8 rows and 8 columns and has a stage completion date of 2623.
* The second layer will consist of 36 blocks, in a 6-by-6 format with a stage completion date of 2983. This is the first layer that requires a block to be placed atop another block, which would require a crane or some form of scaffolding such as an [[platform mound#Platform mounds - other cultures|earthen ramp]] used as an [[inclined plane#history|incline]], although, by at least 2023, placement was already using a crane.<ref name=":0" />
* The third layer will consist of 16 blocks arranged in a 4-by-4 format with a stage completion date of [[4th millennium|3143]].
* The final, fourth layer will consist of 4 blocks, arranged in a 2-by-2 format, which upon completion will complete the structure. The completed pyramid will have taken just shy of a decade less to build than Wemding's age at the time that the first block was laid.

The Zeitpyramide (lit.'time pyramid') is a work of public art by Mancini (1932–2018) under construction in Wemding, Germany. The pyramid began in 1993, the year of the town's 1,200th anniversary. With a new block added every ten years, the structure should consist of 120 blocks when complete after 1,190 years, in the year 3183.[1]

Concept

The town of Wemding dates back to the year 793 and celebrated its 1,200th anniversary in 1993. The Zeitpyramide was conceived by Manfred Laber (a local artist) in June 1993 to mark this 1,200-year period and to give people a sense of what the span of 1,200 years really means.[1]

One block is scheduled to be placed every ten years, taking 1,190 years. This time includes the initial block placed at the beginning of the project, which explains the apparent off-by-one error of ten years.[2] So far, the blocks have all been concrete, but the material of future blocks may be altered in future generations depending on availability of materials.[3]
