Madonna SS. sotto il mistero della Natività

The simple faҫade is divided into three sections by pilasters, with the central section slightly taller than the sides to give the building a more vertical appearance. Under the gable, a pointed arch motif, created by local bricklayers after the war, enriches the structure. They used cement and gravel from Bolsena to redo the plaster and make it more resistant to the weather and the salinity brought by the south winds.

Inside, the church features three naves illuminated by pointed-arch windows. In December 1986, a polychrome ceramic depicting the Madonna delle Api (Madonna of the Bees) by Mario Vinci of Acquapendente was placed above the main portal, in a Gothic niche with the inscription: “NON EST OPUS SIMILE OPERI TUO” (there is no job like yours). A plaque inside the bell tower bears the inscription: “Ps. JACOBUS / MONALDUS / JO. FRANCISCUS / 1577”, indicating with certainty that the final construction of the church was carried out by and at the expense of the three brothers Pier Giacomo, Monaldo and Gian Francesco Monaldeschi della Cervara. 

The church has undergone multiple renovations over its 400-year history, yet it retains its essential structure and serves as a vital part of Trevinano’s cultural and spiritual heritage. Originally, the naves were covered by a simple roof, not vaults. The presbytery was narrower and behind the high altar there was a corridor that served as the sacristy, since the current one was only built around 1750. There were no side altars as there are today, but there was the painting of Saints Peter and Paul and from 1584, that of the Rosary.

On the high altar there was a painting depicting Canaan’s wedding, considered to be of “excellent brushwork”. However, towards the middle of the 18th century, Marquis Arimberto Bourbon del Monte had it removed and replaced with the current one depicting a blissful San Lorenzo Martire with the Virgin and Child and little angels. Although well-made, the author of this work remains unknown.

The report of the Pastoral Visit in 1782 describes the church as one of the most beautiful in the diocese: vaulted with three well-proportioned naves and adorned with seven stucco altars. The ones of the Sacrament and St. Anthony of Padua by the famous Cremoni brothers, particularly stand out.

In 1925, the church which had been damaged by the earthquake of 10 September 1919 (which struck the eastern slope of Monte Amiata), underwent restoration work. The work, carried out by the engineer Rocchi of Acquapendente, involved the demolition of the central vault which was replaced with a wooden Florentine-style decoration, the transformation of the rectangular windows into Gothic arches, the repair of the damaged walls and the construction of a new bell tower with three bells.

After two years of work, the church was solemnly reopened for worship on 29 June 1926. The event was celebrated in the presence of the Bishop of Orvieto, Monsignor Salvatore Fratocchi, with the participation of the town's musical band and the ‘Schola cantorum’ of Acquapendente. Cardinal Gasparri sent a telegram with the Holy Father's blessing.

In 1945, further restoration work was carried out on the façade and in the following years, several interior modifications took place, such as, the renovation of the presbytery with a new altar and travertine balustrade in 1956 and the improvement of the artistic ciborium in 1983.
