View from the dome of St Peter's, Rome, Italy. Built to a plan initially conceived at the turn of the fifteenth century by Donato Bramante (1444-1514) and finished off, heavily modified, over a century later by Carlo Maderno, Saint Peter's is a strange hotchpotch of styles, bridging the gap between Rennaisance and Baroque eras with varying levels of success. Inside is Michaelangelo's Pieta, completed when he was just 24.
