The Nonantolan List of 1366 includes a Church in the village of Montechiaro, dedicated to Saint Justine who was martyred during the reign of Diocletian in the 4th century.
Its white, yellow and rose-tinted façade was the backdrop to the mysterious assassination of parish priest Don Arcangelo Marconi, the illustrious scientist’s uncle, in 1865. But this was not the only event linking this hill to Marconi and his family: in 1427 Cardinal Ludovico Alemanni, papal legate, instituted the County of Montechiaro and nominated Giovanni Giacomo Grifoni (from whom the Marconi home, nearby Villa Griffone, gets its name) as count, with his male descendents to inherit the title.
