Mithraic Altar approximately 40m east of the Hutton Monument

The Mithraic Altar, located approximately 40 meters east of the Hutton Monument, is a significant structure made from Ketton stone, flint, and pebbles. It features a rectangular pedestal measuring about 2.30 meters by 2.55 meters, which is set on a plinth.

The altar has a rustic base made of coarsely treated Ketton stone, resting on a substantial block formed from uncut pieces of flint, with a stone foundation beneath. Above this base, the die is crafted from knapped flint and adorned with a beige pebble-encrusted frieze in a torus shape. Each corner of the die features carved lion's paws that extend to the corners of the rustic base, from which large upturned volutes, carved to resemble acanthus leaves, rise to the top of the die. The entire structure is topped with a coarsely worked stone cap that has carved folds of drapery along the edges.

Inscriptions are cut into Ketton stone slabs shaped like classical tablets, positioned on the upper part of the die on the west and east sides. Some letters show traces of black paint, with one side featuring cuneiform text and the other side displaying Greek inscriptions.
