Church of Santa Maria di Collemaggio
This is the most celebrated basilica in the Abruzzi (closed in the wake of the damage caused by the 2009 earthquake), begun in 1287 on the orders of Pietro da Morone, who became Pope Celestine V in 1294. The huge façade with rectilinear embellishments is distinguished by its geometrical designs in white and pink stone, and pierced with rose windows. On the left flank of the basilica stands the Porta Santa, a fine richly decorated Romanesque doorway. Inside is Celestine's Lombard Renaissance style tomb.
