The recent discovery, between the Church of Santa Maria delle Grazie and the cemetery in the S. Lorenzo district, of a square structure, probably a small italic-roman temple, and of the ceramic fragments found during a test carried out by the Archeological Superintendance of Chieti, are dated between the republican age and the early imperial age. Old discoveries of several burial tombs and numerous fragments of vases collected in Fiorelli in various occasions around the Church of S.Lorenzo, Antonio De Nino’s discovery of ancient shrouds in the Vicenna district and the dug-out tuff tunnels, found next to the cemetery, that branch out into different directions and traces of a mosaic floor consisting of sufficient elements to sustain the idea that this was where a built-up area once lay.

In 1092 the norman Ugo di Girberto, known as Malmozzetto, who lived by Longobard law, donated the Monastery of St.Benedetto, which was constructed by Bishop Trasmondo, as well as all his possessions including those in Acciano to the Church of St. Pelino on April 5.

In 1183 in Lucio III’s seal the following churches were mentioned: St.Pietro, Santa Petronilla, St.Lorenzo, St. Comizio and Santa Maria in Acciano.

In 1223 in the seal o Onorio III, the Church of Sancti Antonini in Azano is mentioned.

In 1294 Celestino V passes through Acciano and performs a miracle, reported by Marino: "While passing the village of the said castle of Acciano on his way to L’Aquila to receive the crown of the Apostolate to which he was appointed, he cured Dorricello, the brother of Berardo di Gordano of Acciano of epilepsy, by his benediction, as Velletta d’Acciano (witness 35) and Odorisio d’Acciano (witness 37) reported".

In 1316 Tommaso d’Acciano, by order of King Robert, is taxed in relation to his possession of a fourth of the village.

In 1360 the land of Acciano is not yet registered among those of those of the Valvense Diocese. Cronologically, Acciano is united to the city of L’Aquila, later given up by Francesco di Cantelmo (1419) and then becomes part of the city, but King Ladislao confiscates it from the latter as a sign of punishment for having supported the party of Luigi d’Angị.

In 1383 Carlo 111 of Durazzo donates Acciano to Matteo Gentile, brother of the Bishop of L’Aquila, for the rebellion of Caterina Cantelmi, the daughter of Restaino and wife of Bartolomeo of Rillona.

In 1409 the city of L’Aquila retakes Acciano from those King Ladislao had entrusted with it. It therefore becomes Crown property becoming one with the same city, so contributing to the payment of taxes like all the other zones of the surrounding country-side. In this period the boundaries with Rocca Preturo and Goriano Valli are marked which are also part of the surrounding country and Molina which instead is not part of it.

In 1417 Acciano is bought by L’Aquila, later becoming the estate of the Scaialenghi, Strozzi and Piccolomini.

In 1419 with her Royal Power Queen Giovanna II, "united and incorporated the land to the City of L’Aquila, so that it was an incorporated and attached unity, almost a member of its body, seeing that all the other land belonged to the Territory of L’Aquila".

In 1529 Prince d’Oranges concedes the territory of Acciano along with 62 other castles, to various Spanish captains. It was then sold by D.Pietro di Toledo for 20,000 ducats.

!n 1533 Acciano and the land of Beffi is owned by Giacomo di Scalegni, who was succeeded by his son Carlo and then Ludovico.

1534 is the year reported on the portal of the three-nave Church of S.Pietro and S.Lorenzo.

In1546 the wife of Annibale Libero of Acciano has "La Cappella della Pietà" built in the Church of Santa Maria delle Grazie, reserving the patronage for her husband and heirs.

In 1561 Ludovico sells the estate of Acciano to Gio. Carlo Silveri Piccolomini for 25,000 ducats.

In 1573 the heirs of Notar Pietro di Sante de Galli of Acciano build the Chapel Saints Simone and Giuda in the Church of St.Pietro.

In 1669 the owner of the land of Acciano and Beffi is Ferrante Silveri Piccolomini.

In 1798 with the March 29 deed for Notar Luigi Palumbo of Naples, Marquis Giovanni Piccolomini, heir and successor of the so-called Gio Carlo, sells the estates of Acciano and Beffi with their respective Villas of Socciano and St.Lorenzo to Vincenzo Treccia for 6,700 ducats.
