This St Peter property was formerly known as La Ferme de la Chapelle, and it is said that there was a chapel here. This is confirmed not only by the name but also by the presence of a symbol for a church building on the 1795 Richmond map. But, as Joan Stevens notes in Old Jersey Houses, there is no record of a chapel in this area.
She wrote that the building is 'very small indeed' - only 14ft 6in by 11ft externally, with a small, round arch at the east end. It is built of Mont Mado granite with St Mary granite for the gable edge stones.
- "The stones of the wall show weathering and great age. The arch is not quite symmetrical under the gable, but as the two side walls are uneven in height, considerable alteration may have taken place at various times. It is also possible that the arch has been inserted from elsewhere, for it is very curious indeed to have a chapel sited east-west, but with the door at the east end. This is not impossible, and one authority states:'Many of the primitive Christian churches had their altar at the west and their entrance at the east'. If this is the case here it makes it a very old chapel indeed. It is just possible that it was the Priory of St Peter, but this is generally thought to have been situated near the parish church.
