Made famous by Matt Parker of Stand-up Maths on YouTube, the Wemding Zeitpyramide (Time Pyramid) is a pyramid consisting of 120 1.2m x 1.2m x 1.8m (modeled* as 12mm x 12mm x 18mm) concrete blocks arranged in even squares and was designed to celebrate the 1200th anniversary of the German town's founding. Wemding was founded in 793 and the Zeitpyramide's first block was laid in 1993, with subsequent blocks being placed every 10 years. It makes sense that you place a block every 10 years for 1200 years for a total of 120 blocks. However, having placed the first block in 1993, the last block will be placed 10 years early in 3183 rather than the 2400th anniversary in 3193. A prime example of the off-by-one error common in mathematics and programming!
