The  () is a work of public art by Manfred Laber under construction in Wemding, Germany. The pyramid was begun in 1993 – the 1,200 year anniversary of the town. It will take another  years to complete and is scheduled to be finished in the year 3183. The structure is intended to consist of 120 blocks when complete, with a new block added every ten years. In September , the fourth block will be installed, making the project  complete.

Concept 
The town of Wemding dates back to the year 793 and celebrated its 1,200 year 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. 

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. 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.

Artist 
Manfred Laber was born in Wemding in 1932 and studied painting at the Hochschule für Bildende Künste in Berlin in the 1950s. He has other artwork on permanent display on the Isla San Antonio, and in Alcanar, Spain, and Mormoiron, France. Alcanar is also his part-time place of residence.

Construction

Current progress 

The time pyramid is located on a concrete pad on a rounded hilltop, the Robertshöhe, on the northern edge of Wemding. The first block was placed in October 1993. The  third and most recent block was placed at 16:14 on 29 June 2013. Following the construction schedule, the fourth block will be placed on 9 September 2023.

The project's initial financing was mostly achieved through donations by local companies, which, for example, supplied the materials for the concrete slab for free.  The project is administrated by a foundation based in Wemding.

Speculative future progress 

A model of the final artwork is exhibited at Wemding, at the Haus des Gastes. If the time pyramid project proceeds according to plan, it will fall into four stages based on tier layer.

Base tier 
The base layer, measuring , will consist of 64 blocks arranged in 8 rows and 8 columns and has a stage completion date of 2623.

Second tier 
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 earthen ramp used as an incline.

Third tier 
The third layer will consist of 16 blocks arranged in a 4 by 4 format with a stage completion date of 3143.

Fourth tier 
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 layer will have taken just shy of a decade less to build than Wemding's age at the time that the first block was laid.

Completion 
The pyramid, when completed in the year 3183, is scheduled to consist of 120 stone or concrete blocks, each measuring  long,  wide and  tall. Adjacent blocks are separated by gaps of half a block or .
