It is one of the twelve "Ancient Parish Churches" of Jersey.

In ancient Latin documents the church is referred to as Ecclesia Sancti Clemtentis de Petravilla in Gersuis which translates to "the Church of St. Clement on the estate of Peter in Jersey".

[1] The church's origins lie with a privately owned fort which is thought to have been destroyed during the Viking raids.

Construction of the stone church began around the year 911, starting with a chapel; now the nave.
