Pyramid of Cestius

The Pyramid of Cestius is an ancient Roman funerary monument in Rome constructed as the tomb of Gaius Cestius around the late 1st century BC. It is notable for its steep-sided pyramid form faced in white marble and for surviving largely intact.

The monument stands about 36.4 metres tall with a square base roughly 29.4 metres on a side and is faced in Carrara marble. Its striking geometric form and marble cladding make it one of the more instantly recognisable ancient structures in Rome.

Built for Gaius Cestius, a member of the Roman collegium of priests known as the Septemviri Epulonum, the pyramid dates to about 18-12 BC. In the 3rd century AD the structure was incorporated into the Aurelian Walls, which helped protect it from later demolition and reuse.

The pyramid sits in the Ostiense area of Rome near Porta San Paolo and the Protestant Cemetery, adjacent to the Aurelian Walls. It is readily visible from surrounding streets and is often combined on visits with nearby historic sites.

• Dimensions: Rises to about 36.4 metres and has a roughly square base about 29.4 metres on a side, faced in white marble.
• Origins and preservation: Originally built as a tomb for Gaius Cestius and later incorporated into the Aurelian Walls, making it one of the best-preserved ancient Roman pyramids.
