Long Lost Medieval Chapel Uncovered in Northern England

The remains of a long-lost medieval chapel, comparable to some of the greatest in Europe, have been uncovered at Auckland Castle in northeastern England.

Historical documents show that a two-storey chapel, described as ‘sumptuously constructed’ and ‘exceedingly good,’ was built at Auckland Castle, Bishop Auckland in the early 1300s. It was created for  Bishop Antony Bek, (Prince Bishop of Durham between 1284-1310), a great warrior and one of the most powerful and influential men in Europe at the time.


Despite it being larger than the king’s own chapel at Westminster, and with pieces of carved stone weighing the same as a small car, the exact location of the 14th century chapel has remained a mystery since its destruction in the 1650s, following the English Civil War.

Now, following years of archaeological excavations, Bek’s Chapel has finally been discovered and the full extent of its spectacular scale will be revealed to the public in a special exhibition beginning next month at Auckland Castle. A new reconstruction image of the medieval building will be on display in the exhibition, alongside finds uncovered by archaeologists from Durham University and The Auckland Project, the charity that owns and manages Auckland Castle.

The foundations of Bek’s Chapel were found during digs over a five-month period, which revealed that the walls of the medieval chapel were 1.5m thick, 12m wide and 40m long internally. Archaeologists also found huge bases for internal columns, the buttresses along the chapel’s sides and even part of the floor. And over 300 pieces of elaborately carved stone were excavated, from fragments the size of a fist up to those the weight of a small car.


The uncovered evidence suggests that the original chapel was a vast structure, reaching towards the size of continental chapels such as Sainte-Chapelle in Paris and featuring a timber ceiling and huge pillars with decorated stonework. Archaeologists believe the chapel’s size, scale and decoration would have been a statement of the status of Bishop Bek, who as Prince Bishop of Durham held remarkable powers to mint coinage, raise armies and even rule on behalf of the king.

“It’s difficult to overstate just how significant this building is, built by one of the most powerful Prince Bishops as a statement of his power,” says John Castling, Archaeology and Social History Curator at The Auckland Project. “Finally discovering the chapel was a fantastic moment for the whole team, which included students from Durham University and volunteers from The Auckland Project. We were all surprised by the sheer scale of the chapel and it’s great to be able to share the reconstruction image which shows a building that would have stunned visitors, from all walks of life.”

In the months following the discovery of the chapel, archaeologists from The Auckland Project and Durham University have been working with a panel of archaeological experts, including Architectural Historians Tim Tatton-Brown, Tim Ayers and John Crook, to create a reconstruction of Bek’s Chapel, as it would have looked in the 14th century.


The team mapped details from elements of comparable buildings, including kings’ chapels, cathedrals and minsters, to suggest the kind of glasswork, carved stone and roof construction that would have featured in Bishop Bek’s original chapel. Stuart Harrison, Archaeologist at York Minster, recorded the geometry of the discovered foundations and stonework to reconstruct the framework of the original building. Meanwhile, Andy Gammon combined the information with his own research to bring the Chapel to life through a coloured reconstruction, with a cut-away opening up the chapel’s interior as well as an aerial view from the South West.

“It’s been great to work with a number of archaeologists and artists to create this reconstruction drawing,” added John Castling. “Andy’s illustration which is the result of extensive excavation, collaborative work and individual research, is a fantastic way to bring Bek’s Chapel to life in the early 14th century.”

Professor Chris Gerrard from Durham University’s Department of Archaeology, commented “This is archaeology at its very best. Professionals, volunteers and Durham University students working together as a team to piece together clues from documents and old illustrations using the very latest survey techniques to solve the mystery of the whereabouts of this huge lost structure. We are really looking forward to returning to Auckland for another season of excavations.”


The team of archaeologists from The Auckland Project and Durham University will return to Auckland Castle this summer to continue their excavation of Bishop Bek’s Chapel where they are hoping to uncover more of the south side of the building.

Some of the uncovered carved stonework will be on display for visitors to examine in an upcoming exhibition Inside Story: Conserving Auckland Castle at the Bishop Trevor Gallery at Auckland Castle. From Monday, 4 March to Sunday, 6 September the exhibition will also reveal more about the processes and techniques used in the recent conservation of Auckland Castle.

Auckland Castle is open 10am to 4pm, Wednesday to Sunday, admission is £10 for adults, £8 for concessions and £3 for under-16s, and includes entrance to the Bishop Trevor Gallery. For more information on how to get involved in future archaeological excavations at The Auckland Project visit
