The exterior is not very impressing, but you can see one unique thing about this church - the rose windows show that this is a Gothic church, the only Medieval church in this style in Rome. The façade was added in 1453, and is attributed to Meo del Caprina. It was paid for by the Orsini family. At the end of the 16th Century, Carlo Maderno gave the church a Baroque façade, then restored in the 19th century to its present neo-medieval state.
