The cavane (cavàne) are shelters for boats tipical of Venice, its lagoon and all the navigable rivers.
Maybe the word has the same origin of hut (capanna): in fact in the oldest pictures of the city, the cavane are depicted as shelter covered with straw, like huts. Over the years this type of shelter has been used also for buildings like noble palaces or warehouses. On the side overlooking there is a river and in some cases it is protected by a wood or metal closing.
In the terminology of the gondoliers and the taxi drivers the expression “andar in cavana” means the rest of the boat and so the end of the activity. The operation typically consists of berth in a private area, cover the ship with protective towel and close the access (and the passenger compartment in case of water taxi).
Cavàne in Codevigo and in Millecampi Valley
The plenty of canals and boats in valley Millecampi necessitated building shelters suitable to keep vessels undamaged from bad weather. For this reason the cavane are easliy viewable along the banks in Fogolana area in Codevigo.
