The historical Bourbon del Monte Palace in Piancastagnaio (Siena
Italy) dates to the 17th century and represents an uncommon example of feudal architecture in Tuscany. It was inhabited until the end of the ‘80s of the last century when
due to the high degree of instability achieved
it was declared unfit for use by the Public Authorities. The Palace lays on a sloping site
on the edge of fractured trachyte blocks mixed with alluvial deposits. It is characterized by four floors above ground and a basement at the South-East corner
while the North façade has two floors. Severe degradation phenomena of the building consist of multiple cracks diffused along the external and the inner masonry

furthermore
significant water infiltration from the floor has been observed in the South-East basement since the ‘80s. Previous investigations have shown that the Palace has undergone two distinct settlements systems: one dates before the ‘70s and may have caused the cracks along the South wall of the building

the other
more recent and probably related to the water infiltration on the basement
may have caused the damage to the South-East wall. This paper investigates the source of this second settlements system by modeling and analyzing a 2D soil section close to the South-East corner of the building. Firstly
the collected geotechnical and geological data and the modeling of the analyzed section are presented. Afterwards
the results of the numerical simulations are shown and discussed
