"In the grounds of Sant'Agnese's is a small round church, one of the most beautiful in the city. It dates from the years immediately following the death of Constantine in 337, and is among the oldest Christian buildings to have survived almost complete; it is still in use as a church." (p.176)
Beside the church of Sant'Agnese is the Mausoleum of Santa Costanza, the daughter of Constantine, who built a church in honour of Saint Agnes.
The interior of the Mausoleum, the
oldest church in Christendom that is still in use as a church, and a
masterpiece of early Christian art.
