Villennes-sur-Seine (French pronunciation: [vilɛn syʁ sɛn] ⓘ, literally Villennes on Seine) is a commune in the Yvelines department in the Île-de-France in north-central France.

[3] The construction of Saint-Nicholas church started in the eleventh century and ended in the twelfth under the initiative of the abbey of Saint Germain-des-Prés.

In the eighteenth century, the church was associated with the Coulombs en Eure et Loir abbey and major renovations began.

[5] The presence of the first and second companies of the 286th infantry regime in Villennes-sur-Seine disturbed daily life starting in July 1915.

Once all the wheat was requisitioned from the Maroles farm, Mr. Laumonier had crops brought in from Saint Germain-en-Laye to feed the villagers.

Most were from Allied countries such as England, the United States, Belgium or Italy, but the town shows records of hosting people from Argentina, Brazil and Spain.

In 1927, l'Île du Platais (otherwise uninhabited) welcomed a new population of vacationers in bungalows or tents in the Physiopolis center.

Physiopolis brought in consistent amounts of people all throughout the summer and made Villennes-sur-Seine a weekend getaway destination for the Parisian upperclass.

[5] On a night in July 1944, a Germain plane crashed into a house on the Marolles farm, killing a couple in their sleep.

The debris spread on a radius of 30 meters and to this day, a pit can be pointed out on the Marolles farm that corresponds to the location of the crash.

Having been attacked the night prior, the soldiers arrested four men and brought them into the basement of a home: Michel and Jacques Jeunet, Alfred Boursinhac and Rodolphe Gerha.

[6] A path along the Seine from the southernmost point of the town to the northernmost goes along the waterway with views of the water and the old homes of Villennes-sur-Seine.
