In the 12th century, along the west-east direction on the eastern edge of the Cesi building, located on the Colfiorito plateau south-west of Serravalle di Chienti, between Taverne and Corgneto, the church of St Callisuts was built. In the 17th century it was renovated, and in the 18th century enlarged with a sacristy, a bell tower and a rectory. Due to numerous seismic events in the 20th century, restoration work was carried out with a new design of the main façade in the 1960s by architect Paolo Castelli. The rectory was built leaning against the south and east fronts of the church, thus only free on the opposite sides. The main west façade consists of three flanking volumes: on the left, the remarkable square-based, plastered belfry, with the belfry cell marked by four round brick arches and a hipped roof covered with tiles, in the centre, the hall hut made of pink stone ashlars, with a rectangular portal with a white stone frame, a high oculus with a moulded stone frame and two rectangular windows at the sides, half-height, on the right, the plastered rectory, marked in the centre by a rectangular window. The north side elevation is characterised, on the right, by the imposing bell tower, and, on the left, by the long plastered surface that joins the church to the rectory, with three rectangular windows, of which only the first on the right illuminates the interior of the hall.
