Palazzo dell'Abbondanza or Triglia, vicolo Rosselmini
One of Administartions typical of the city of Pisa was the Abbondanza (Abundance), established in the mid-fourteenth century by Andrea Gambacorti and entrusted to six citizens, called i Sei del Biado, Officiales super copia et abundantiam grani et biadi. This institution remained in force until 1768. The structure on the side of palazzoTriglia, or dell'Abbondanza, which overlooks Vicolo Rosselmini, vaguely recalls a fortification, or an embankment. The alley is one of the most evocative of the whole city, with arches and bridges that give a sense of continuity to the complex, built near the hospital of San Canuto, mentioned in 1258 and annexed to the 11th century church of San Cristofano. The embankment, or piaggione, hides approximately 52 holes for the conservation of grain, over which today we find a beautiful private roof garden, with exotic plants such as the Japanese medlar and a tall redwood. The palace, the result of several combinations of civil and religious medieval buildings, also had a stufa, or drying room and the scrittoi, or accounting studies. We do not know if this deposit corresponds exactly to the medieval seat of the abundance, but the quantity of silos inside suggests a public rather than private use.
