Sant'Ippolito e Cassiano in Sant'Ippolito
A church at the site, also known as the parish church of St. Hippolytus in the Alps (or Visia) was originally constructed in 998. The existing church is a 12th-century reconstruction with minor later additions. It is likely that the church was a renovated building of Lombard (eighth century), as is indicated by the saint to whom the church is dedicated. The small town of Sant’Ippolito of Vernio sprung up around the church.
The plain façade facing the main square retains the original 12th-century sandstone with a later inserted rectangular window, replacing an earlier lancet. The remaining walls are made with irregular stone masonry from the 13th-century. The 17th-century choir connects the Campanile or belltower, with the 12th century crypt. The belltower is square with a belfry consisting of four undecorated, single windows.
The church has a single-aisled nave terminating in an apse. On the side walls of the mullioned windows were opened (the low mullioned windows were characterized by the arc in a monolithic structure devoid of decoration). The left side of the church opens on the town square. The building still dominates the square. Along the left wall are the remains of later restorations and modifications: three rectangular windows and a single window characterized by the monolithic structure of a lowered bow. The portico connects the church to the sacristy. Beneath the porch is a doorway to the church decorated with a classical pediment. The façade opens to another window that has remains of the original lancet. The rest of the glass is devoid of decoration. On the sides of the original facade is visible signs of the eaves and the roof elevation. The building was built with local sandstone masonry, however, because of subsequent reconstructions, the parish is composed of several stratigraphic units.
The interior is characterized by a single nave covered by wooden trusses. The nave ends in a rectangular apse with a vaulted ceiling. This is surrounded by a round arch that opens on the end wall. The interior was remodeled in the 18th century including the remaking of wooden doors, the addition of confessionals, a high altar and several side altars.
Most of the stone walls are bare. The first altar on the right houses an altarpiece depicting the Deposition of Christ (1579, Giovanni Bizzelli, pupil of Alessandro Allori. The altar to the left has a Madonna of the Rosary (Florentine school of the late 17th century). The sacristy has an altarpiece depicting Adoration of Shepherds (1503, Girolamo Ristori).
