Leaving form Siena, you can cross the Crete Senesi until you get to the first major city, Asciano. In this lunar-like territory, you will be able to see the characteristic geological formations of the Crete: the Calanchi and Biancane. The former are deep recesses in the land caused by torrential water flow, while the latter are soft, beige-coloured hills that have been rounded by atmosphere agents. This is where the precious and fragrant Crete Senesi truffle is harvested.
Once in Asciano, you can start by visiting the Church of Sant’Agata, which despite dating to the 11th century, is home to two Sienese Renaissance masterpieces: a Madonna and Child by Signorelli and a Pietà by Il Sodoma. Your visit to the town can continue to the late-Gothic Church of Sant’Agostino. Before heading to the first stop dedicated to well-being, enjoy a view of piazza del Grano, home to a travertine fountain made by Paolo Ghini, a beautiful trace of 15th-century sculptural styles.
