At this date fourteen local families still used the abbey church as parochial but this, unusually, did not save it from demolition, the parishioners being transferred to nearby St Peter and St Paul's Church in the area. It has been conjectured that due to the short space between them, the parish church may have been the abbey church, although Claire Breay's "Cartulary of Chatteris Abbey" discounts this idea, citing that historical documentation clearly defines two separate churches. A range of the cloister buildings survived as part of a mansion known as Park House. This was demolished in 1847 and the site has now completely vanished beneath streets and housing, although the "Park Streets" of Chatteris mark the boundary of its walls and several buildings contain stone originating from the abbey. A large portion of the town was destroyed by a great fire in 1310, which destroyed the nunnery and a large portion of the church, leaving only sections of the base of the tower.
