La Creusille is a harbor on the left bank of the Loire river, located in the southern part of Blois, France.

[5] From the 17th century on, market gardening, river transportation, fishing, tanning, and the hotel business flourished, and their growth exceeded the capacity of the shoreline.

All the remaining water mills were destroyed, but the submersible dike was readjusted in order to divert the river's flow to the right bank and thus away from La Creusille, making it easier to moor boats.

In 1717, a dike was built in the extension of the harbor and towards the East: the operation dried up the La Bouillie river channel and thus linked the former Evenna island to the left bank.

Now that goods and people could reach Paris in a few hours (as opposed to several days by boat, the duration of which could vary according to direction, season, weather...), La Creusille gradually became a shipyard.

[9] Today, the port has given way to an urban park on the left bank of the Loire river, complete with a leisure area.
