The Time Pyramid (German: Zeitpyramide) is a work of public art by Manfred Laber under construction in Wemding, Germany. The pyramid, begun in 1993, at the 1,200th anniversary of Wemding, will take another 1164 years to complete and is scheduled to be finished in the year 3183. As of 2019, the first 3 of its scheduled 120 concrete blocks have been placed.  
The town of Wemding dates back to the year 793 and celebrated its 1,200th anniversary in 1993. The time pyramid 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 (see Fencepost error) in total. The material of the blocks used is not fixed and may be altered in future generations depending on availability. 
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. 
The pyramid, as far as it exists today, is 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 6.5-tonne (6.4-long-ton; 7.2-short-ton) third and most recent block was placed at 16:14 on 29 June 2013. 
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.  It is unknown if or how the project would be continued if the administrative foundation stopped existing. Assuming the project proceeded according to plan, it would naturally fall into stages by tier.
The planned base layer, measuring 13.8 by 13.8 m (45 by 45 ft), consists of 64 blocks arranged in 8 rows and 8 columns with a presumptive stage completion date of 2623 — some decades after Wemding's hypothetical bimillenary.
The planned second layer will consist of 36 blocks, in a 6 by 6 format with a presumptive stage completion date of 2983. This is the first layer that requires a block be placed atop another block, which would require a crane or some form of scaffolding such as an earthen ramp used as an incline.
The planned third layer will consist of 16 blocks arranged in 4 by 4 with a presumptive stage completion date of 3143.
The planned final, fourth layer consists of 4 blocks, arranged in 2 by 2, upon completion of which the structure will be finished, having taken just shy of a decade less time to build than Wemding had been in existence at the time the first block was laid.
The pyramid, when completed in the year 3183, is scheduled to consist of 120 stone or concrete blocks, each measuring 1.2 m (3.9 ft) long, 1.2 m (3.9 ft) wide and 1.8 m (5.9 ft) tall. Adjacent blocks are separated by gaps of half a block or 0.6 m (2.0 ft).
The significance of the number 12, 1,200 years and 120 stones is coincidental[clarification needed (see talk)], with a construction date beginning in 1993 being the most practical. The reason for this is that the closest similar combinations before and after were or would have been possible only in 1633 (7 by 7, 840 years, 84 blocks) and 2443 (9 by 9, 1,650 years, 165 blocks).
