Just in front of the Church of Santa Maria Assunta was built the Spedale della Scala, 13th century. A branch of Santa Maria della Scala in Siena for pilgrims on the Via Francigena in the Middle Ages.
In addition to being a grancia of the Spedale della Scala in Siena, it constituted the main hospitable structure of San Quirico d’Orcia. The buildings that made up the former hospice have preserved the fourteenth- and fifteenth-century wall structures of the grange, with its large inner courtyard, well, and several rooms, including a beautiful architraved loggia on the second floor.
Three slender and elegant small columns remain in the outer loggia, and a characteristic well, which bears the date May 1543.
In a slab of the same well, there is, in the center, a frieze in high relief and, at the top, a staircase surmounted by the cross.
