The largest Renaissance church in Abruzzi stands out from afar with its impressive facade and dome. It was built after the death of Bernardine from Siena (1380-1444), a Franciscan and one of the most effective and widely known preachers of his day, who lived in L'Aquila for a long time. Its layout and structure is very different from the Romanesque-gothic churches typical of the city. The unique façade, designed by Cola dell'Amatrice, consists of three orders in the three doric, ionic and corynthian styles to express the 16th century ideal of a perfect fusion of Greek and Latin classical forms with the Christian heritage.
The Baroque interior is 96m long and was completely rebuilt after a terrible earthquake (1703) which nearly destroyed the whole city; it is divided into three aisles that join under the dome. The ceiling is in wood and sequin gold and contains in the centre St. Bernardine's monogram "JHS" paintings and in the other fields. In a chapel in the right aisle there is St. Bernardine's mausoleum, the most relevant Renaissance sculpture work in Abruzzi, by Silvestro dell'Aquila, a pupil of Donatello's.
