Palazzo Marsili-Libelli

The palace is adjacent to the taller Palazzo Marsili with a crenellated roofline and mullioned second and third story windows, and which stands at the corner of Via di Città and Via del Castoro.

The origins of the Piccolomini family were linked this house as is evidenced by the coat of arms of Pope Pius II placed over the central entry portal, sculpted by Urbano da Cortona.

The coat of arms has two cherubs lofting a papal tiara above a shield held by struggling angels.

The pointed arches at street level with internal rounding are characteristic of Sienese Gothic.

The second floor has a small chapel with a 17th-century altar with a painting attributed to Dionisio Montorselli.
