The municipality of Deliceto, located at 575 meters above sea level in the Dauni Mountains, forms a geographical and cultural link between the Irpinia area to the south and Capitanata to the north. It is arranged in a horseshoe shape along the Carapellotto river and has a population of 3,588 inhabitants. The village is characterized by a spiral layout designed for defensive purposes and contains a series of medieval architectural features such as gates, towers, and sections of walls that are now integrated into buildings and homes. Dominated by the imposing Norman-Swabian-Angevin Castle, the village has preserved its narrow, cobbled streets and stone and brick buildings with characteristic rooms featuring distinctive barrel vaults, cross vaults and widespread nail vaults, including numerous places of worship, such as the Church of the Annunciation dating back to the 9th century, the Church of St. Anne and the Dead built on the foundations of the 15th-century Church of Purgatory, and the 16th-century Convent of St. Anthony. Excavations have confirmed the presence of the Daunians between the 9th and 5th centuries BC and then the Romans.

The village, which contains an important underground heritage, is surrounded by extensive wooded green areas. Deliceto has ancient origins, most likely dating back to protohistory. Its embryo was the district of “Pesco,” made up of caves dug into the front of the Elceto spur by Oscan-Italic populations. These underground dwellings corresponded to the human need to shape the reality built within the natural landscape. With the Romans, it became a basic settlement, a camp built where the “Piazza Alta” district is located. This fortified settlement, built in an area where elm trees grew, was called “Elceto,” from which the name ‘lliceto’ and finally “Deliceto” derived.

Deliceto was elevated to the status of a sub-Apennine lookout for the Duchy of Benevento under the Lombards, who built the first nucleus of the Torrione in the second half of the 9th century. In the 12th century, under Norman rule, it became a sub-fief, first of the county of Loretello and then of others. It retained the same status under the Swabians and Angevins, who were responsible for the expansion of the castle. It became a marquisate in 1463 under Ferdinand I of Aragon, who granted it to his son-in- law Antonio Piccolomini, nephew of Pope Pius II, born Enea Silvio Piccolomini. The marquis settled in Deliceto with a colony of Albanians.

Under the Piccolomini family, in the 15th century, the convent of Santa Maria della Consolazione was built in Valle in Vincoli at the request of the Augustinian monk Blessed Felice da Corsano. Under the Piccolomini family, in the 15th century, the convent of “Santa Maria della Consolazione” was built in the locality of “Valle in Vincoli” at the request of the Augustinian monk Blessed Felice da Corsano. The fiefdom of Deliceto, while remaining state property, passed from the Piccolomini family to the Bartirotti family and from them to the Miroballo family, who were related to each other. In 1744, at the convent of Santa Maria della Consolazione, St. Alphonsus Maria de' Liguori founded the third house of the Redemptorist order, which over the years hosted many saints and blessed figures, including St. Gerard Majella.
