Sepolcro di Annia Regilla (già detto Tempio del Dio Redicolo)

To the left of Via della Caffarella, in a narrow street descending towards an ancient mill around, you can see the Roman monument also known as the temple of the god Redicolo.

To the left of Via della Caffarella, a narrow road descends towards an ancient mill around which a number of rural buildings have been erected over time. Here a Roman monument is preserved, also known as the temple of the god Rediculus, based on a legend formed in the 17th-18th centuries that located the Campus Rediculi, a place sacred to Rediculus, the god who protected the return of the Romans to their city, at this spot on the Caffarella valley floor. The monument has the characteristics of a quadrangular sepulchral building, which in the elevation borrows the forms of a polychrome brick temple, with a pseudo-peripteral podium of Italic type and Corinthian order, according to a typology that in Rome is compared to other sepulchres from the age of the Antonines (2nd century AD).

The building's front faces north towards the Almone, the stream revered as a deity by the Romans that crossed the Caffarella valley floor on its way to the Ostiense and Tiber rivers.

The tomb is commonly attributed to Annia Regilla of the very noble Annii family, who around AD 140 married the very rich and famous Herod Atticus, tutor of the future emperors Marcus Aurelius and Lucius Verus, bringing him a dowry of vast lands on the Appian Way and who died in AD 160. The identification is based on the existence in the area of the Appian Way of a sanctuary called Triopio, dedicated by Herod to the memory of his wife, and on a series of inscriptions mentioning Regilla, from the area of the basilica of St. Sebastian and the tomb of Cecilia Metella. Recently, some scholars have refuted this hypothesis, arguing that the so-called Triopian inscriptions do not directly mention a burial ground dedicated to Regilla (but rather a heroon), which instead would have been found in Greece as Herod's (according to what is expressly stated in an inscription now lost).
