The apse basin is decorated with a 17th century painting,
The Madonna of the Snow and Saint Valentine, patron saint of Penna in Teverina.
The Church of St. Maria della Neve of Penne in Teverina was mentioned at least in 1476, when it was still a small countryside parish, which became the nucleus of the first inhabited centre that would later have been fortified. The structure was enlarged and completely renovated in the 16th and 17th centuries.
The original structure was probably located in the same spot of the current one, but it must have been a very simple structure, certainly smaller than the current one. It was transformed during the 1600s; there were many payments made in 1639.
On the main altar there must have been, at least since the 15th century, a painting depicting the Lady Mary and the saints Valentine and Sebastian, replaced in 1700 by the current painting.
Today the church features 17th century shapes that are extremely simple and linear: a very simple façade and a gable roof on which stands a little bell tower with two small arches.
