Dome

Close frontal view, depicting central portion; The first definite dedication is from a plaque on the church dating to 1128. It was constructed in and from the ruins of the Forum Holitorium [Olitorium] and its temples, along with a jail (carcer) which a tradition (supported by Pliny's history of Rome) states was sited in the temples' ruins. Spolia from all these ancient remains is still apparent in the church's construction, most particularly three columns from the Temple of Juno Sospita which are incorporated into both the 10th century and 1599 north facades of the church. The church was rebuilt in 1599, with a new facade by Giacomo della Porta (though the medieval campanile was not altered). Source: Wikipedia; http://en.wikipedia.org/wiki/Main_Page (accessed 7/30/2010)
