St Peter's Church, Firle is a Grade I listed Church of England parish church in Firle, East Sussex, England, dedicated to Peter the Apostle. It stands adjacent to Firle Place, seat of the Gage family since the 15th century, who have long patronised the church.
Part of the benefice of Glynde, Firle and Beddingham, Reverend Peter Owen-Jones has been the rector of St Peter's since 2005.
A Saxon church in Firle is attested to before 1066, belonging to the Abbey of Wilton. Rebuilt sometime in the decades following the Norman Conquest of England, the living first passed to the Abbey of Grestain at le Bec Hellouin in Normandy. Between 1197 and 1204, Abbot Robert of Grestain gave Firle Church to the Dean and Chapter of Chichester Cathedral. A reset round-headed doorway in the north aisle dates from around this period.
By the 13th century, the nave had reached its present length, and the chancel and west tower were constructed. In the 14th century, north and south aisles were added, featuring arcades on octagonal piers and a broad chancel arch. Clerestory windows and a cinquefoil in the east gable also date from this period.
During the 15th century, square-headed aisle windows and a south aisle extension were introduced, along with a rood stair. In the 16th century, a chequered flint and stone south porch was added, with a moulded entrance arch, and buttresses were added to the tower. Around 1595, the north chapel - known as the Gage Chapel after its patrons - was built with a crown-post roof.
Restoration in 1867 included a tiled reredos on the chancel east wall sometimes attributed to William Morris.
Notable interior features include:
Buried in the churchyard of St Peter's are artists Vanessa Bell (d.1961) and Duncan Grant (d.1978), central members of the Bloomsbury Group who lived at Charleston Farmhouse, not far from Firle, from 1916 until their deaths.
