At the time of the Dominant, to move from one place to another, boat transport - by water - was privileged, while the connections between pedestrian areas - through the use of bridges - were considerably lower than the current ones: a true network of micro islands.
Over time, changing habits and increasing the importance of pedestrian traffic led to the need to build new bridges: first in wood, then with stone structures and only in the last two centuries of metal. At the time of manufacture, the builders realized that some of them could not rest perpendicularly between one support point and the other, but rather obliquely, sometimes for two calluses that did not meet, other times because the banks did not match. Thus the term crooked bridge was coined.
Although there are very many oblique bridges in the city, only 7 of them are labeled as a crooked bridge.
The crooked bridge to Santi Filippo and Giacomo is met walking behind the apse of the Church of San Giovanni Novo, along the road that connects Campo dei Santi Filippo and Giacomo to Ruga Giuffa; a few steps from the bridge, a curious access leads to an accommodation that in the past was an ancient Venetian residence from the 16th century.
The crooked bridge of Sant'Aponal owes its name to its asymmetrical steps, as one is perpendicular to the river while the other, which goes towards the foundations, is parallel to it; in 1837 it underwent a rearrangement. The residence where the famous Bianca Cappello was born and lived her childhood with her family is located near this crossing.
To go towards Santa Marta, a crooked bridge is visible in Santa Maria Maggiore which connects the fondamenta dei Cèreri with calle Camerini; the singularity of this crossing is that, going down, it divides into two: one part goes towards Calle Teren and the other towards Calle dei Fontegheri.
The crooked bridge in San Martino was erected in 1953 - in fact the iron structure demonstrates its youth. It is located at the confluence of the Arsenale stream with the Ca 'di Dio stream and holds a record in Venice: it is considered the coarsest and roughest bridge in the lagoon city, due to its not at all elegant sides.
The crooked bridge in Santa Maria del Giglio is also called Caotorta and crosses the Rio della Verona. After crossing it and walking along a short foundation, you will come across a new bridge dedicated to San Cristoforo.
The crooked bridge in San Boldo connects the sestieri of Santa Croce and San Polo and, if he participated in a competition, he would win the most crooked bridge scepter in Venice, despite having a harmonious and graceful figure.
The crooked bridge in San Marcuola, which to a hasty and inattentive eye seems the result of an architect's whim, is located halfway between the Venice Casino and the Church of Saints Ermagora and Fortunato and connects a small square with Rio Terà drio the church.
All the other bridges, in addition to the seven listed, and also positioned in a slant, instead take on names that take the name of a personality or physical places. Easily, this identification system - not linked to the term crooked bridge - wanted to avoid creating too much confusion considering the excessive amount of city bridges. Examples are the Ponte delle Guglie, the Marco Polo bridge behind the Teatro Malibran, the Conzafelci bridge in Santi Giovanni e Paolo or the Savio bridge in San Giacomo dall'Orio.
