Église Saint-Georges de Trappes, Gothic church in Trappes, France

Église Saint-Georges de Trappes is a Gothic church defined by four corner buttresses that support its distinctive quadrangular bell tower, which stands as the oldest surviving element of the structure. The tower's prominent position and design establish the visual character of this house of prayer.

A church dedicated to Saint George stood at Trappes by 1003, reached by steps because it lay about 60 cm below the street and flooded in heavy rain. The bell tower collapsed in 1599 and was repaired and covered with tiles in 1602. The church was demolished around 1700 and rebuilt from 1701 to 1703, keeping only the quadrangular tower with its four corner buttresses, which survived the bombing of 1 June 1944. The nave was rebuilt in 1964 by the architects Claustre and Jegou.

The church keeps a wooden crucifix damaged in the 1944 bombings and restored in the 1950s by parishioner M. Laurent; it is said to come from Port-Royal Abbey and to date from the 17th century. The baptismal font, placed right of the altar, is Louis XIV period, its basin of Pyrenean marble. The bell Marguerite-Élisabeth, blessed in 1647, cracked between the wars and was recast as two smaller bells still rung today.

The church stands on the Place Monseigneur Romero, where the 15th-century Croix d'Auleau marks the site of the former cemetery; a sign on a post nearby reads "Cimetiere Le Village". The north facade door carries a Roman-numeral inscription recording the 1964 nave reconstruction by architects Claustre and Jegou. The 13th- or 14th-century liturgical basin that survived the 1700 demolition is no longer in the church but kept at the Centre Technique Municipal.

The bell named Marguerite-Elisabeth cracked and was recast into two smaller bells during the interwar period. This transformation shows how church installations were adapted to meet changing needs.
