Walking north to Arbia, Sigeric took a way through the Ombrone valley, reaching the bridge of Buonconvento (known from written sources starting with the 9th century). From there, it went back, closely following the Roman road-network across the whole valley, to reach Ponte d’Arbia (Spatial calculations and archaeology: roads and settlements in the cases of Valdorcia and Valdarbia, Stefano Bertoldi, 2013).
Ponte d’Arbia has been documented since the early Middle Ages , however the event that made her go down in history is the death of Henry VII, August 24, 1313, less than a kilometer from the village. It is suggested by some historians that the death of Henry VII of Luxembourg, Emperor of the Holy Roman Empire, was due to poisoning. During his short reign, Henry reinvigorated the imperial cause in Italy, divided between the Guelf faction (who were sympathetic to the papacy) and Ghibelline faction (sympathetic to the German Holy Roman emperors).
