In ancient «valley of Paestum », then said of Fasanella, furrowed by four rivers and many streams, was Fasanella surrounded by walls with in the North side a fortress, seat of the county of Fasanella and Corneto. Pandolfo, Count of Capaccio and Corneto and brother of Guaimario V, had from Teodora of Tusculum, including many sons, John, to which, in the division of the county after the assassination of his father, who rushed to defend the prince on the banks Salerno, touched Corneto. John married Ageltruda from Sessa, from him was born Jordan who still possessed Corneto in1137.

Other documents help to clarify the intricate succession of local lords. In fact, Malfredo, Count of Castle of Fasanella, with a Diploma of 1086, gave to Athanasius, abbot of a monastery building near the church of St. Nicholas of Frasso, the church, mills and surrounding lands. It is an important document because it informs about the rise of the «monastery of St. Nicholas of Frasso», whom we still read in a document of 1134. With this award, Lightning Fasanella, son of Guaiferio, and his wife Emma, ​​donated to Abbey of Cava, with the consent of the bishop of Paestum, Alfano, of his chapter and its clergy, the church of St. Nicholas «de lo Frassu », church existing before of the Diploma of 1086 and certainly of Italian-Greek foundation, as evidenced by its donation to an abbot.

In 1183, Tancredi of Fasanella gave the church of San Lorenzo to the monastery and to the church of s. Nicola «de lo frasco » of Abbey of Cava, to increase the assets of the monastery and the church. Also this diploma is interesting, as well as for the anathema in the case of harassment for possession or eviction, especially for the predicate of some soldiers present at confirming of the existence of disappeared villages situated there. Tancredi and his brother William were sons of William, soldier, that from village of Postiglione, had taken the predicate. William have had the barony, «iure francorum » and therefore indivisible, of Postiglione. Aquara, Castelluccio, Civita Alburno, Controne, Corneto, Pantoliano, Ricigliano. San Zaccaria, Selvanegra and Serre. From his wife, «marital nomine », had the Lombarddivisible Barony of Fasanella with Albanella, Capaccio, St. Peter, Corneto, Ottati, Roccadaspide and Sant'Angelo. Tancredi had two daughters, Alexandrine and Filippa.

The first one married to Pandolfo from Fasanella bringing a dowry of the «state » of Fasanella, Filippa married Pandolfo’s brother, Riccardo, bringing a dowry of the «state » of Postiglione. As is known Pandolfo and Richard were among the conspirators of Capaccio, to whom Frederick II appropriated assets by razing, as tradition, many villages, including Fasanella. Not everybody however, agree on the destruction of this town. There are some documents which prove that he was alive even after Fasanella, possibly because it was reconstructed by the population, which then abandoned it and moved to Sant'Angelo. From the document of the visit of the abbot Thomas to Monastery of St. Nicholas we read about the consistency of that monastery. At the time of Frederick II, over Pandolfo (he had been imperial captain in Tuscany; after his flight to Rome he was honored by the pope; to the times of King Charles he was a Roman senator, vicar in the Principality, Governor of Capua in 1275 and executioner in the ground of Otranto), among the Fasanella should be mentioned Theobald Francis, Riccardo and Roberto (killed by Frederick II) Matthew, Gilberto and Landulf exempted from feudal service, and Thomas, knighted and called by the feudal service in Achaia to accompany Charles on his journey to Sicily and then Marshal in Rome in 1271.

In «Liber inquisitionum » we read of Pandolfo and Riccardo, whose assets were confiscated by Frederick II. As mentioned, Pandolfo managed to escape capture and repair in Rome, Riccardo and Roberto suffered mutilation written by Walter Okra in an accurate report to his king of England and the horrible death that followed, which is said in Collenuccio. The wife of Pandolfo, Alexandrine, had meanwhile died childless. The second daughter Filippa, who married Frederick Thomas Saponara died soon after, widowed and escaped into exile filming husband marrying Gilbert of Fasanella. To them, after the death of the Emperor, were granted the fiefs of Corneto, Roccadaspide and Albanella, the latter feud then assigned to the cousin of Filippa, Richard, who died without heirs in the days of King Manfred, so Albanella returned to the Crown and King Manfred then donated it to Count Giordano Lancia.

Other estates had been granted by King Manfred to Giovanni da Procida, who had married Pandolfina, daughter of Julius from Postiglione. These continued to possess all those feuds until the advent of Charles of Anjou, who returned them to Pandolfo. By process we learn of the number of inhabitants (104 fires =people 520) and of the value of the barony. Pandolfo had so returned Aquara, Albanella, Bellosguardo, Campagna, Castelluccia, Controne, Genzano, Roccadaspide, and S. Pietro in Galatina. Belonged to him still the fiefs of Contursi and S. Severino of Camerota that King Charles granted then to Thomas Sanseverino. Pandolfo died without heirs, so all his property back to the Crown (1284) that granted them (1291) to Thomas Sanseverino.

To Thomas succeeded Errico who married Ilaria Lauria, which held the barony after the death of her husband, having Postiglione, Fasanella and Serre. In the period it came on a fight, just for Fasanella, with Thomas, Count of Marsico, guardian of Thomas, son of Errico Sanseverino. In an instrument drawn up on 15 September 1371, at the request of the church of Fasanella, the witnesses were all priests of the village. Of Fasanella is still news in some inventories. In one of 1339, we found that it was Sir Roger of Sanseverino and that Santangelo was held as a sub-fief by Bartolomeo Sanseverino; another of 1412 show that the castleman of Fasanella was Piran from Scalea, which was later granted a sub-fief; from inventory of 1420 detects an union of interests between Fasanella and Bellosguardo.

The Barony of Fasanella now consisting of Fasanella, Santangelo, Bellosguardo, with the hamlets of Ottati, Ottatello, Civita and Contursi, then passed to Predicasso Barile, which sold it in 1426 to Thomas Sanseverino, with consent of the Queen Giovanna II. The barony was held by the Sanseverino family until 1528 when Duke of Martina, G. Battista Caracciolo bought it from the Prince of Bisignano, Pietrantonio Sanseverino, then barony consists of Santangelo, Ottati, Ottatello, Civita, Contursi and Postiglione. It seems that in 1530 the barony had been in possession of Michere Soria. But by a privilege of Bellosguardo is that in 1532 was lord Alfonso Caracciolo, confirmed then to James Caracciolo on 20 October 1543.

In 1557 and in 1549 was lord Petraccone Caracciolo, Duke of Martina, which in 1558 sold the barony to Portia Caracciolo. To this was succeeded his son Cesare Loffredo that in the January 8, 1565 sold the barony of Santangelo, Ottati and Ottatello to Marcantonio Pepe. This one then gave it as a dowry to his daughter Portia who in 1581 married Belisario Acquaviva d 'Aragona who sold the barony in November 1594 to Lucrezia della Marra. It should be noted that since 1598 there are any news of Fasanella. Giustiniani assures that from that year is only news of Santangelo a Fasanella about the sale of the Duchess of Nardo to Lucrezia della Marra of Santangelo a Fasanella and Ottati with hamlet of Ottatello for d. 22,000. In 1662 the creditors demanded the judicial administration of the barony, then auctioned.

It was bought by James Capece Galeota, Regent of Collateral that on 2l October of 1664 had the title of Duke.This one later married Eleanor Carafa, daughter of Prince Louis of Castel San Lorenzo. From her was born Francis who inherited the estates. He was succeeded by James, who had only two females (Cornelia and Antonia). Cornelia married Fabrizio Spinelli, count of Bovalino, Duke of Castelluccia and Altavilla, which became so «marital nomine », Duke of Santangelo, Ottati, Bellosguardo, Civita and Corneto. After three years Cornelia, childless, widowed, married Louis Sanseverino, Prince of Bisignano, who «maritale nomine », became Duke of Santangelo and other fiefs. After the death of her parents Francis sold Ottati, Bellosguardo and Civita (1774) to Thomas Mariconda, Prince of Caraguso, dead in Ottati on November 16, 1777.

He was succeeded by his brother Andrew. Santangelo, however, remained to Capece Galeotas to refute of the mother Cornelia, Princess of Bisignano, and Antonio Capece Galeota. For resignation of Fabio (27 March 1784) Santangelo, with the title of Duke,and the estate called Corneto or Corleto went to his brother Luigi. With Real privilege on October 26, 1781, he obtained legal header in Cedolario (27 March 1784). At his death, feuds and titles passed to his son Francesco Maria (October 22, 1783 m. 15 May 1838) and from him to his son Charles (17 February 1824 - August 14, 1898), who, by Ministerial Decree on 15 February 1888, obtained, even with Neapolitan patrician, legal recognition. Few news in Antonini, who says that «The hamlet owes its name to the cave of St. Michael the Archangel, where fled the population of Fasanella, when at the time of Federico II was dismantled». Giustiniani puts the village in an alpine place chalky and stony, wet from Fasanella that animated mills, throwing then itself in the Sele.
