The exhibition dedicated to Ambrogio Lorenzetti, was held from 21 January 2017 to 8 April 2018, at the Santa Maria della Scala complex in Siena.
Thanks to a series of targeted loan requests for works from the Louvre, the National Gallery, the Uffizi Galleries and the Vatican Museums, the exhibition wanted to retrace the artistic life of Ambrogio Lorenzetti, bringing together a whole series of paintings to Santa Maria della Scala which, mostly, were produced precisely for Siena citizens and for churches in the city.
