How is the wood Venice is built on not decomposing over time?

(Not sure about the flair.. sorry)
Wooden beams in earth (like with fences) rot over the years and break.
I was under the impression that this was because of water.
Shouldn’t Venice “sink” because of rotten beams?

The conditions of the surrounding soil actually protect the wood from rotting, the dense mud/sediment and lack of oxygen won’t allow any life forms to decompose the wood. The same phenomenon (over millions of years) is also what [turns wood into stone](https://en.wikipedia.org/wiki/Petrified_wood).
