900-year-old Anglo-Saxon place of worship has been discovered underneath a church

Engineering expertise supporting heritage, accessibility, and community use

MCA was appointed to deliver the structural and civil engineering services for the reordering of St Cuthbert’s Church in Darlington, working from RIBA Stages 3 to 5. Our team supported the project from early design development through technical coordination and into construction, supporting a scheme centred on improving accessibility and expanding community use of this important place of worship.

The £2.5m programme introduces new amenities including WCs, a café and flexible meeting areas, alongside the relocation of the font and font cover. A key element of our work involves enabling the installation of a new ground‑bearing slab to support the revised internal layout and future functionality of the space.

Responding to a significant archaeological discovery

During excavation works to lower the Victorian floor, the project team uncovered substantial Anglo‑Saxon remains beneath the church - a discovery that has attracted national attention, including coverage by the BBC.

Archaeologists from The Archaeological Practice of Newcastle (APN) have identified the exposed walls as likely belonging to a church built shortly after the Norman Conquest, around 1080. These findings sit beneath the existing north and south arcade columns and are slightly offset from the later Norman structure above. The remains, approximately 1.2m wide and formed of roughly‑worked facing stones around a rubble core, rest on deep cobble foundations. Digital recording and 3D imaging are now being used to document the discovery in detail.

Adapting the engineering strategy with care

The presence of these early medieval remains introduced an unexpected challenge for the new slab installation. MCA is now working closely with the wider project team to adapt the engineering design in a way that protects the archaeology while maintaining the robustness and longevity of the structural solution.

Our approach balances best‑practice conservation principles with the technical demands of a modern reordering scheme. This includes developing sympathetic detailing, reconsidering load paths and ensuring that any interventions remain fully reversible where required.

Supporting the future of a historic community landmark

St Cuthbert’s is a Grade I listed building of exceptional heritage value and ongoing community significance. As the design evolves, we remain committed to delivering engineering services that respect the past while enabling the church to serve its congregation and wider community for generations to come.
