The Sanctuary of the Our Lady of the Bath of Castiglion Fiorentino is situated in the point wherein, according to the Catholic tradition, the Our Lady appeared and sang a curative source of water. It was initially a small oratory that was replaced, between 1524 and 1527, from a building that remained unfinished. It was enlarged in 1711, but the current building, a latin cross with coverage barrel, dates back to a remake of the years 1874-87 to the work of the architect castiglionese Pietro Mancini.
