This paper aims to describe the importance of bridges – from the semiotic point of view, stressing their capacity in connecting nature and culture. It is arguing forthe importance of establishing technosemiotics as a separated chapter in sign system studies. The author mentions some famous bridges, such as the bridge over the river Kwai, Brooklyn Bridge, Puente de Alcantara (in Spain), bridges over the sea by the order of Xerxes and Caligula, other Oriental and European bridges, the Mostar Bridge (in (...) Bosnia) and the Peruvian suspension bridges, as in the novel by Th. Wilder: The Bridge of San Luis Rey. The illustrations are from Machinae Novae by Faustus Verantius (published 1616 in Venice).
