Karlsruhe Pyramid

In the centre of Karlsruhe's market square stands a pyramid built of red sandstone — one of the most unusual landmarks in Germany. The pyramid is not decorative: it marks the tomb of Margrave Karl Wilhelm, the founder of Karlsruhe, who had himself buried at the centre of his radiating city plan in 1738.

The current pyramid, about 7 metres high, was constructed in 1823 to replace an earlier wooden structure. It stands in the middle of the cobbled market square, surrounded by the neo-Gothic Rathaus (city hall) and the city's Protestant church. The combination of a market square, a church, and a pyramid-topped tomb makes this one of the more unusual central squares in Europe — entirely typical of the Enlightenment rationalism that shaped Karlsruhe's original design.

A story
The pyramid on the market square marks the tomb of the city's founder, Margrave Karl Wilhelm of Baden-Durlach. Karl Wilhelm died in 1738, having founded Karlsruhe only 23 years earlier — and was buried beneath the very centre of the city he designed. The original wooden pyramid over the tomb was replaced by the current sandstone version in 1823. It is the only pyramid in Germany used as a burial monument on a functioning city square.
