The large town's position on the estuary of the River Touques was a natural establishment of a fish dock.
It is situated on the River Touques, along the Boulevard Fernand Moureaux and downstream from the Pont des Belges.
In 1934, mayor Fernand Moureaux, desiring to emphasise the traditional character of Trouville, as opposed to Deauville's grand chic[1] hired local architect Eugène-Maurice Vincent to build, in 1936, a modern building inspired by the Lieutenance house and the porch of Saint Catherine's church of Honfleur.
On 23 October 1992, fishing trawler the Laiss'dire shipwrecked one nautical mile from the entrance to the port of Trouville-sur-Mer.
Due to bad weather, the search for the bodies of the ships' three sailors was in vain.
