A town in the province of L'Aquila, situated on the slopes of Mount Calvario, Pescocostanzo dominates the plateau overlooking the Quarto Grande. Although the name is mentioned for the first time in a document of the XI century, the discovery of graves dating from the III century A.D. evidence that the town was founded by the Romans. Between X and XI century the presence of a small fortified village is witnessed, around which, in later centuries, developed several houses. Partially destroyed by an earthquake in 1456 and thanks to the government of Vittoria Colonna, the town was rebuilt and enriched with several valuable artworks that feature a perfect mixture of Baroque and Renaissance styles.
