Église Saint-Jean-Baptiste de Vélizy-Villacoublay, Modern Catholic church in Vélizy-Villacoublay, France.

The Église Saint-Jean-Baptiste is a Catholic church at 16 rue Clément-Ader in Vélizy-Villacoublay. Its double nave, seating about 700, leads to a raised central altar; the walls are concrete with glazing along their upper section. The bell tower, about 25 metres high, is made of two concrete blades. The low side building has a flat overhanging roof on rectangular concrete brackets and pale vertically ribbed cladding.

Construction of the church began in February 1970 to accommodate the growing population following aviation industry development in Villacoublay. The building emerged during a period of urban expansion driven by industrial growth in the area.

The church features abstract stained glass windows by François Chapuis created in 1983 and a ceramic wall mural by Katarzyna Pawliszewska-Lavocat at the base of the tower. These artistic works define the interior and give the space a contemporary artistic character.

The church stands at 16 rue Clément-Ader in Vélizy-Villacoublay, in the Yvelines, and belongs to the parish grouping of Vélizy, Buc, Jouy and Les Loges. The entrance faces the street, with the low ribbed-panel hall on one side and the concrete clock tower on the other. Look for the cross and clock face on the tower to orient yourself.

The retable installed in 2019 is the work of Sister Claire Schmeltz and shows the baptism of Christ. It stands inside a church consecrated on 24 January 1971 by Louis Simonneaux, bishop of Versailles, and placed under the patronage of Saint John the Baptist and Saint Denis.
