The Gothic Palazzo Agostini (Picture 1), aka Palazzo dell'Ussero, has a façade made in the 15th century and vestiges of the ancient walls which were built even before 1155. It is named after the Caffè dell’Ussero (Lungarno Pacinotti 27), housed in the palazzo, a historic gathering point inaugurated in 1775 and still open, where the first Italian Congress of Scientists had its venue in 1839.
