Pyramid

The Karlsruhe Pyramid is a pyramid made of red sandstone, located in the centre of the market square of Karlsruhe, Germany. It was erected in the years 1823–1825 over the vault of the city's founder, Margrave Charles III William. The pyramid is regarded as Karlsruhe's second emblem, the city's absolutist layout in the shape of a folding fan being the first.

The pyramid's central location was originally occupied by the Lutheran Concord Church, a Baroque timber-framed building. When Karlsruhe grew at the beginning of the 19th century, the church became too small and obstructed the southward expansion of the city and its market square. It was demolished in 1807, and initially a wooden pyramid was erected over the city founder's vault as a temporary measure before moving it into the new main church.
