More just recently, seawalls were constructed in 1623 in Canvey Island, UK, when fantastic floods of the Thames tidewater happened, triggering the construction of defense for more events in this flood-prone area. Ever since, seawall design has actually ended up being much more complex and intricate in feedback to an enhancement in products, technology, and an understanding of just how coastal processes run.

This was primarily due to French engineers that had actually created (and preserved) a huge rock seawall during the time when the city was a French nest.
