Eutropia converts one of the halls in Helena's palace at Rome (the Palatium Sessorianum) into a chapel. This chapel later becomes Santa Croce in Gerusalemme.
Helena's mausoleum at Torre Pignattara (so called from the pignatte, or earthen vases built into the vault to lighten its weight) is round in shape, and contains seven niches or recesses for sarcophagi. One of these sarcophagi, famous in the history of art, was removed from its position as early as the middle of the twelfth century by Pope Anastasius IV, who selected it for his own resting-place. It was taken to the Lateran basilica, where it appears to have been much injured by the hands of indiscreet pilgrims. In 1600 it was carried from the vestibule to the tribune, and thence to the cloister-court. When Pius VI added it to the wonders of the Vatican Museum, it was subjected to a thorough process of restoration which employed twenty-five stone-cutters for a period of nine years.

The reliefs upon it are tolerably well executed, but lack invention and novelty. They are partly borrowed from an older work, partly combined with various sources in an extraordinary manner; horsemen hovering in the air, and below them, prisoners and corpses scattered around. They are intended to represent a triumphal procession, or possibly a military decursio, to which allusion has been made above.
It may appear indiscreet and even insulting on the part of Anastasius IV to have removed the remains of a canonized empress from this noble sarcophagus in order to have his own placed in it; but we must bear in mind that although the Torre Pignattara has all the appearance of a royal mausoleum, and although the ground on which it stands is known to have belonged to the crown, Eusebius and Socrates deny the Helena was buried in Rome. Their assertion is contradicted by the "Liber Pontificalis" and by Bede, and above all by the similarity between this porphyry coffin and the one discovered in the second mausoleum of which I have spoken, -- that of S. Constantia, on the Via Nomentana.

The palatium Sessorianum is in possession of the Empress Helena, whose name is preserved in an inscription on a base of a statue, now in the chapel of S. Elena. Other inscriptions referring to Helena found in the neighborhood.
Founding of the basilica and donations of Constantine the Great or of one of his sons; among these perhaps also a relic of the Holy Cross.

Reconstruction of Santa Croce in Gerusalemme by Lanciani based on existing ruins, late 19th century. The amphitheater is named Castrense. The ruins to the northeast of the sessorian hall is a Templum Veneris et Cupidinis (Temple of Venus and Cupid).

Above these arches the transverse walls rose to a height if 18.25 m. above the present level, thus reaching almost the height of the original roof; the last remains of these transverse walls above the arches are preserved in the gouges in the two long sides of the ancient construction.
[T]he diameter of the columns which today divide the nave and the aisles, is precisely 88 cm. which corresponds almost exactly to the thickness of the arches and the insets. Thus it would be a working hypothesis to assume that these very columns were the original supports for the transverse arches.
