From the second half of the XVI C. the Toscolano community, in order to fulfil a vow, used to have a mass celebrated there every 25th of the month. In 1581 Battista Sgraffignoli left in his will his paper mill in contrada Lupo, in the Papermills Valley, for the celebrations and money to finish the construction of the church and its decoration. As stated in his will, the interior decoration was made between 1583 and 1590 with paintings representing the life of the Virgin and placed between frescoed architectural frames. The statue of the Virgin enthroned in the apse dates back to the half of the XV C, and has a XVII C. wooden altarpiece.</div>'
