Dragados, 2003. «Ponte vecchio» bridge in Bassano: An historical «excursus» Carla Alberta Scapin The bridge of Bassano is a work offered to the configuration; as a voluntary or obliged point of citizens, the visitors, and the students of the matter, as pause, as a clot for inhabited buildings, business an example of historical and architectural activities and handicraft. lt is offered like a support to permanence; a manufacture which was first built as a the multiple sides of the city, able to create a place, a simple crossing and that has became through the vital space, loaded with means, functions and years the real symbol of the city. historical deferments. The bridge becomes a monument and is delivered The departure point is the locality in which the up as an element of great importance for the city wooden manufacture is laboured: Bassano del Grappa; Bassano is certainly one of the most singular Venetian citizens that has risen along the borderl ine between the plain and the hill. The bridge thus becomes the artefact needed to combine two natural separate places; a crossing that contains in itself the implications of a separation. Bassano means Brenta, Channel of Brenta and Valsugana. lt is in this axis that the history ofBassano has always run, along with the history of its wooden bridge, as testified by a wide list of images and documents that reconstruct its shape since the Medieval Age. The new connection can be without any doubt considered as an important sign of environmental modification produced by human beings. From the 1200's and through the centuries the bridge has always remained respectful towards the tradition: several generations of carpenters, builders, designers have perpetuated its original shape, which has always been considered by the local population as Figure 1 a sort of limes.

In fact, the first norms that guaranteed the respect of the manufacture came from the old city Statutes of 1259 and 1295, which protected it thanks to a detailed system of rules: the duties. Nevertheless the receipts brought to the municipal cashes by the transport of goods and the human passage were not always enough to cover the expenses for the simple maintenance of the lumber. Some new kind of protection towards the fluvial atmosphere were adopted just after the quick expansion of the Venetian possessions, with the constitution of a new organization: the State of Mainland, in contrast with the State of Sea.] The bridge in the centuries The more reliable document testifying the existence of the bridge in Bassano is the written of Geraldo Maurisio, who in its Cronica describes the meeting, happened in 1204, between Ezzelino III, coming from Brescia, and its servants, in «platea, quae est a capite Pontis Baxianis» (Maurisio,I726). This place seems to be the ancestor of the present structure, a fact Figure 2 which is also proven by the loan contracted by the Rilievo topografico del Brcnta (Topographical relief of city of Bassano in 1222 «for laborerio pontis Brenta).
