The Collegiate Church of San Michele Arcangelo is the place of worship most dear to the Solofran people and among the most famous of the entire province of Avellino.

Built from 1522 by the will of the Universitas of Solofra in a historical period marked by the term "golden age" of the local tanning market, the Collegiate took the place of the pre-existing Pieve di Sant'Angelo e Santa Maria, of Byzantine origin, in accordance with the urban development of that time. The religious building has gone through a very long phase of construction and, in the course of its history, has been the victim of several earthquakes and some fires, including that of 1721 which caused considerable damage to the Collegiate Church: It was after this episode that the structure changed considerably appearance, changing its style from Renaissance to Baroque. Hit again by the earthquake of 23 November 1980, it was reopened to worship in 1986.

Today the Collegiate Church of San Michele Arcangelo has a longitudinal plan, a Latin cross, preceded by a beautiful Baroque facade: the latter is flanked by a bell tower in Romanesque style and respects the internal division into three naves, punctuated by pillars with capitals in Ionic style that hold the frames with moldings. The three portals, the work of Neapolitan workers who tell the story of San Michele Arcangelo, are finely carved and topped by as many windows, of which the largest is located above the main portal and is embellished, on the top, from decorative patterns with shells.

Once inside the Collegiate Church, the viewer’s gaze lingers on the 42 canvases characterizing the wooden coffered, depicting scenes from the Old and New Testaments, attributed to Giovanni Tommaso and Francesco Guarini (1611-1651) and embellished with a gold coating that also distinguishes the pulpit, the choir with the organ and the altarpiece on the high altar. In addition to the sublime works of the two Solofran painters, the building also houses other masterpieces, such as the "Pentecost" by Angelo Solimena (1629-1716), above an altar located in the right aisle, and the "Coronation of the Virgin" by Giovan Bernardo Lama (circa 1530-1630).
Finally, the Chapel of the Immaculate Conception, raised above the body of the collegiate church, as well as the crypt containing the Chapel of Saint Jude Thaddeus also preserve interesting artistic evidence.

A true jewel of Baroque art, the Collegiate Church of San Michele Arcangelo is considered as one of the most beautiful and precious places of worship in Irpinia.
