The city was first mentioned in medieval Latin documents as pontem sarasinam in 1137. In 1237 it was mentioned as de Ponte Sarraceno and in 1303 as ponte sarracino. Some historians translate it as The Bridge of the Saracens and see in it a reference to a tenth-century Arab invasion of the lands that later became Switzerland. It is essential though to have a bridge to use the Bernina pass and it would make sense to build this before the confluence of Ova da Bernina and Ova da Roseg due to the amount of water to cross.
