In the necropolis the statue of the "Warrior of Capestrano" was found during the work in a field by a farmer. The tall statue depicts an early Italic warrior in full gear, the King of the Vestini tribe, Naevius Pompuledius, executed by the sculptor Aninis. Now the statue is on display in the National Archaeological Museum of the Abruzzi in Chieti.
The Benedictine Abbey of St. Peter ad Oratorium is on the bank of Tirino river, from Capestrano. The church was built in AD 752 as part of the monastery of St Vincenzo al Volturno, by the Lombard kingDesiderius. The religious building was edified in the 12th century. It is a church with a nave, two side aisles and a choir. There is only one entrance door with a lintel decorated with vegetal motif. Onto the romanic portal there are two marble relief with the figures of David and St. Vincent Deacon. The façade has a marble square inscription of the Sator Square in Latin. In the 15th century it was abandoned by the monks.
Piccolomini or Mediceo Castle
The castle was built in the 13th century, on the hill next to the Tirino river and the Abbey of St. Peter ad Oratorium in a strategic position at 505 m above sea level. It was a feud of Tolomeo di Raiano in 1240, and was granted to the Acquaviva family in 1284 by Charles I of Angio. Riccardo d'Acquaviva was thus named marquis of Capestrano. In 1462 the Castle passed on to Marquis Antonio I Todeschini Piccolomini d'Aragona, nephew of Pope Pius II, who enlarged the castle with new towers with battlements. In 1579 Marquess Costanza Piccolomini, daughter of Innico Piccolomini, sold the castle to Francesco I de' Medici, Grand Duke of Tuscany. In 1743 the Castle passed on to Charles III of Spain in his capacity as Charles III Bourbon, King of Naples and the two Sicilies. In 1860 the Castle passed on to the Savoyard King of Italy.
