Treviso, a town founded by the Romans, had a great flourishing during the medieval periods and Renaissance. The medieval walls, built in the 12th century, were completely rebuilt in the Renaissance, reducing the number of town gates from 13 to barely 3 gates: Altinia (to reach Alyino on the south-east), Santi Quaranta (to reach Padua and Vicenza) and San Tomaso (to reach Conegliano and Udine).

A characteristic aspect of the town are its frescoes on the facades of old houses, along the portici and inside the churches. Another peculiar characteristic of the town is that it is traversed by canals and rivers. Botteniga, coming from the north, divides into three canals...... La Roggia-Siletto, Buranelli and Cagnan..... which traverse the town and then pour into the Sile River. Portico ai buranelli, the Pescheria and the Ponte Dante are some of the most characteristic places created by these canals.
