Piazza Elio Callisto - Nomentano
First half of the second century AD
It was the tomb of one Helium Callistius, a freedman of Hadrian (117/138)
The common name Sedia del Diavolo (Chair of the Devil) with which this tomb is known is because of its shape: with the collapse of the façade it took the unusual shape of a monumental chair of a bishop, and that turned on the popular imagination
In the area a PREHISTORIC SITE was found dating back to more than 200,000 years ago
