In the countryside of Sepino there is the small convent of "S. Maria degli Angeli", built like a small Portiuncula in 1871 thanks to the collaboration of brothers Giovanni and Carmine Maglieri, one of whom offered the land and most of the building material, the other offered the sum of 200 lire and thanks above all to the will of Father Anselmo from Sassinoro. On November 6, 1871, the foundations were laid and in the following year Father Anselmo began to live there sometimes with Brother Pasquale from Pontelandolfo. It grew bigger and bigger and in 1875 it already contained seven cells on the second floor and all the rooms necessary for a perfect dwelling on the second floor.

The Crypt of Saint Mary is the most important church in the Vallone rupestrian area of Crispiano. It bears witness to religious worship in the surrounding land since its origins in the Middle Ages.
