About
Bishop Bonner's Cottage Museum is housed in the oldest surviving domestic building in Dereham, a row of three thatched, timber-framed cottages standing in St Withburga Lane beside the churchyard of St Nicholas and a few paces from St Withburga's Well. The building is the exhibit as much as anything inside it. Its low doorways, sloping ceilings, tiny rooms and twisting stairs give an immediate physical sense of how ordinary people lived in a Norfolk market town five centuries ago, and its exterior carries an unusual survival: decorated pargeting, the moulded plasterwork that once ornamented East Anglian buildings and now rarely survives in this quality.
The cottages take their name from Edmund Bonner, Bishop of London under Mary I and one of the most notorious figures of the English Reformation, remembered for his role in the burning of Protestant heretics. Local tradition holds that he lived here as curate of Dereham before his rise; the association is old and firmly attached to the building, though it belongs to the same category of town memory as any long-repeated claim about a famous former occupant. What is not in doubt is the survival of the building itself, which came through the great fire of 1679 that destroyed much of Dereham and through the Zeppelin raid of 1915, when the town became one of the first places in Britain to be bombed from the air.
Since 1963 the cottages have served as the town's museum, run today by the Dereham Heritage Trust, whose volunteers steward the rooms, manage the archive and mount a fresh exhibition each season alongside the permanent displays of local artefacts and photographs. Dereham's history gives them plenty to work with: the shrine of St Withburga and the theft of her relics by the monks of Ely, the market and its charters, the poet William Cowper, who spent his last years here and is buried in the parish church, the novelist and linguist George Borrow, who was born nearby, and the twentieth-century town of agricultural engineering, the railway and the two world wars.
The museum opens on a short seasonal timetable from May to September, on Fridays and Saturdays, with a small admission charge payable at the door. It takes well under an hour to see, but the combination of a genuinely remarkable building, an unhurried welcome and displays that change annually makes it a fixture for local visitors as much as for those passing through mid-Norfolk.

💡 Visitor Tips
- The season is short — May to September only, Fridays and Saturdays — so check the Trust's current dates before travelling.
- Look at the pargeting on the outside walls before you go in; it is one of the best surviving examples of the craft in mid-Norfolk and is easy to walk straight past.
- Mind your head. The doorways and ceilings are genuinely low and the stairs are steep and twisting.
- The building cannot be made accessible to wheelchair users; if mobility is a concern, contact the Trust beforehand to ask what can be seen at ground level.
- Walk into the churchyard next door to see St Withburga's Well and William Cowper's memorial — both are part of the story the museum tells.
- Ask what this season's exhibition is; the Trust changes it annually from its archive and it is often the most substantial display in the building.
- There are no toilets in the cottage; use the town-centre facilities before your visit.
- Combine the visit with the Mid-Norfolk Railway, ten minutes away, if you want to make a full day of it in Dereham.
Highlights
The Cottages Themselves
The building is the museum's most important object.
A row of three timber-framed cottages under a single thatched roof, it is the oldest surviving domestic structure in Dereham and one of the best-preserved small vernacular buildings in mid-Norfolk. Inside, the original sloping ceilings, exposed beams, tiny rooms and narrow twisting staircases have not been opened out or regularised, so visitors move through the spaces largely as their occupants did.
That authenticity comes at a price in accessibility, but it makes the experience of the interior quite unlike a conventional gallery — you feel the scale of a labourer's house rather than reading about it.
The Pargeting
The exterior carries decorated pargeting — moulded and incised ornamental plasterwork applied to the render of timber-framed buildings, a craft that flourished in East Anglia and Essex and now survives only in scattered examples. The Dereham panels are among the reasons the building is so highly regarded, and they are best studied from the lane before going in.
Pargeting was both display and protection, weatherproofing the frame while advertising the status of whoever paid for it, and the survival of a decorative surface this fragile on a working cottage for four centuries is genuinely unusual.
Bishop Bonner and the Name
The cottages are named for Edmund Bonner, Bishop of London under Mary I, whose part in the burning of Protestants made him one of the most vilified figures of the English Reformation and earned him the epithet Bloody Bonner in later Protestant tradition. Dereham's tradition is that he served as curate here before his elevation and lodged in these cottages.
The museum sets out both the tradition and its uncertainties, together with the wider story of the Reformation in Norfolk, making the building a useful way into a period usually approached through cathedrals and statutes rather than through a curate's lodging.
St Withburga's Well and the Stolen Saint
A few steps from the museum, in the churchyard, is the spring that rose — according to the story — where the body of St Withburga lay after monks from Ely stole her relics in 974, having judged that Dereham's saint would serve their abbey better than her own town. The museum covers the Anglo-Saxon foundation, the theft, the pilgrimage that followed and the well's continuing place in the town's identity.
It is a startlingly early story to find attached to a small Norfolk market town, and it explains both the size of the parish church and the lane the museum stands in.
Collections
The collection covers Dereham and the surrounding mid-Norfolk parishes and is displayed in a very small historic building, so material is rotated rather than shown all at once. Holdings include local archaeological finds; objects relating to the market town's trade, agriculture and domestic life from the medieval period onwards; material on the great fire of 1679 and the town's fire-fighting arrangements; items connected with St Withburga, her well and the medieval pilgrimage; memorabilia of William Cowper and of George Borrow; nineteenth and twentieth-century shop, school, chapel and household objects; and material on the two world wars, including the Zeppelin raid of 1915 and the Second World War airfields around the town.
The Trust also maintains a substantial photographic and documentary archive of Dereham, which supplies the annual changing exhibition and supports local and family history research.
The Oldest House in Dereham
Interpretation of the cottages themselves — their sixteenth-century timber frame, thatch, pargeting and interior plan — together with the tradition connecting them to Bishop Edmund Bonner.
The Story of Dereham
Displays of local artefacts, documents and photographs covering St Withburga and the Anglo-Saxon foundation, the medieval market, the fire of 1679, the Victorian town, and the two world wars including the 1915 Zeppelin raid.
