Dome

Altarpiece, "Crucifixion", detail; Saint Catherine of Siena is buried here (except her head, which is in the church of San Domenico in Siena). Beyond the sacristy, the room where she died in 1380 was reconstructed here by Antonio Cardinal Barberini in 1637. This room is the first transplanted interior, and the progenitor of familiar 19th and 20th century museum "period rooms." The frescoes by Antoniazzo Romano that decorated the original walls, however, are now lost. Source: Wikipedia; http://en.wikipedia.org/wiki/Main_Page (accessed 2/15/2008)
