The Pantheon, probably built under Trajan, was consecrated as a church by Pope Boniface IV (608-614), with its round niche facing south used as an apse. Almost none of the furnishings of the early church have survived, apart from the encaustic icon of the Virgin Mary, believed to be a portrait by the hand of St. Luke the Evangelist. The consecration of an altar to St Lawrence under Pope Innocent III is recorded in 1209. In 1270, the canons jointly donated a bell tower and bells, which were erected above the ridge of the roof of the pronaos. During the same period, the interior was probably renovated, of which the altar ciborium is documented in a drawing and in some preserved fragments. The signature of Stephanus Magius with the date 1270, once found in the floor of the presbytery, may be connected to this work. Under Pope Innocent VIII (1484-1492), the presbytery plutei were renewed, re-using 6 porphyry columns from the medieval pergula. In the 17th century, under Popes Urban VIII and Alexander VII, the pronaos was restored by removing the medieval structures and integrating the entablature of the left corner of the portico; the bell tower from 1270 was also demolished. On the attic, two turrets were placed behind the roof of the pronaos, which were in turn demolished in 1883. In 1711, under Pope Clement XI, the ciborium and pergola were removed as part of a Baroque renovation of the liturgical furnishings.
