Ellerburn
St Hilda's Church, Ellerburn
A mile north of Thornton-le-Dale, in a fold of the valley with the beck running past, stands one of the oldest buildings for miles: a small church with Saxon stones in its walls, a thousand years of worship behind it, and a nationally important colony of bats in its roof. The story of how the two learned to share the building reached Parliament twice.
Ellerburn is a hamlet rather than a village: a handful of houses, a lane, and a church in a small valley with Thornton Beck flowing just to the south of the church grounds. It sits about a mile north of Thornton-le-Dale and belongs to the same ecclesiastical parish, Thornton Dale with Ellerburn and Wilton, within the Benefice of Moor and Dale, the Deanery of Northern Ryedale, the Archdeaconry of Cleveland and the Diocese of York. Of the churches in that benefice, St Hilda's is described as the mother church, being by far the oldest.
Most people arrive here on foot or by bike from the village, because the walk out is one of the loveliest short walks in the area. What they find at the end of it is a building of real national importance, and a conservation story that is far more interesting, and far more generous on both sides, than the headlines suggested at the time.

The building: Saxon foundations, 11th-century walls
The foundations of St Hilda's are thought to be early Saxon. The structure standing above ground dates from the 11th century, and set into its walls are Saxon fragments and relics that point to something earlier still, possibly as late as the 10th century. Ninth and tenth century carved stones are incorporated in the fabric, which is the clearest physical evidence that a church stood on this spot long before the walls you can touch today were raised.
The building was extensively restored in the 15th century, and again in a campaign of work carried out between 1904 and 1905. During that restoration the architect formed the theory that the chancel arch had once carried a fresco of the Last Judgement, a reminder that a church interior of this age was originally a far more colourful place than bare stone suggests. A new lychgate followed in 1909.
Historic England lists the Church of St Hilda at Grade II*, list entry 1074194, designated on 5 February 1986. Grade II* is the middle of the three listing grades and marks a building of more than special interest, which puts St Hilda's among the more significant buildings in this part of Ryedale. The full designation record is public: Historic England list entry 1074194.
The listing, in brief
Grade II*, list entry 1074194, designated 5 February 1986 (Historic England). Early Saxon foundations, 11th-century structure, ninth and tenth century carved stones reused in the walls, restored in the 15th century and in 1904–1905, lychgate 1909.
Where it sits in the church
Diocese of York, Archdeaconry of Cleveland, Deanery of Northern Ryedale, Benefice of Moor and Dale, Parish of Thornton Dale with Ellerburn and Wilton. Described as the mother church of the benefice, being by far the oldest.
The churchyard and the Dobson monument
The churchyard holds one monument that no visitor misses: a large edifice of red granite topped by a stone finial, dedicated to three members of the Dobson family of Ellerburn. It is emphatically Victorian in scale and confidence, and it divided opinion from the start. The antiquarian Jeffery, writing in 1931, dismissed it as a hideous obelisk erected in the worst of taste. That verdict is his, not this guide's; a century later it reads more as a period piece of taste-policing than as a fair judgement on a family's memorial to its dead.
The bats: a protected colony in a thousand-year-old roof
St Hilda's reached the national press in 2004, and again in 2011, because of the bat colonies roosting in its roof space. The church is home to a large and important breeding population of Natterer's bats, together with at least three other bat species. That matters ecologically as well as legally: bat numbers in Britain fell severely during the twentieth century, and all British bat species are protected under British law, which makes it an offence to harm them or to damage or obstruct a roost without a licence.
Churches are, from a bat's point of view, close to ideal. Thick walls hold a steady temperature, roof voids are undisturbed for most of the week, and buildings of this age offer the sort of crevices that modern construction does not. A colony of this size in a building of this size, however, produces a quantity of droppings and urine that a small congregation cannot simply mop up each Sunday.
In August 2011 services inside the church were suspended, after around a thousand years of almost uninterrupted worship on the site. Walls, floors and the altar were all affected. The congregation, rather than give up the year's rhythm, held their harvest festival outdoors. It is worth being plain about what that means for a rural congregation: the building is not a venue, it is the reason the community gathers where it does.
Finding a solution, and how it was reached
Following representations by the church, Natural England granted a licence to block some of the access points the bats had been using to reach the body of the church. Crucially, the roof roost itself was left intact: many hundreds of bats continued to live in the roof space, with ongoing monitoring of bat activity inside the church. The building reopened in time for Advent and Christmas 2011.
None of that was free. In a House of Commons debate in June 2013 it was stated that St Hilda's had by then spent some £29,000 on mitigation repairs, a formidable sum for a small parish (source: Hansard, 25 June 2013).
Work continued on the technical question of how to keep bats out of the interior without harming the colony. Research carried out in 2013 by the Animal Health and Veterinary Laboratories Agency looked for a workable answer, and following that research Natural England issued a licence to block bat access to the interior while maintaining the bats' access to roost in the roof area. That distinction, interior closed and roof open, is the heart of the solution.
The Bat Conservation Trust responded in October 2013 by welcoming Natural England's search for a way to let people and bats coexist. It noted Natural England's confidence that the safeguards would secure the long-term survival of the bat populations using the church, while adding, fairly, that it was too early to judge the outcome and that monitoring would be what mattered (source: Bat Conservation Trust, October 2013). That is a reasonable position from a conservation body: cautious support, with a request to watch the evidence.
The verdict came in a further House of Commons debate in December 2014, where it was stated that St Hilda's had successfully excluded bats from the interior and that the congregation had been allowed back into the building to worship. The case was presented as a demonstration that perseverance, and working with Natural England, can produce a solution that lets a congregation worship without harming bats (source: Hansard, 11 December 2014).
It is worth resisting the easy framing here. This was never a story of bats as vermin, or of a congregation as unreasonable, or of conservation law as an obstacle. A legally protected and ecologically valuable colony and a working thousand-year-old church both had a genuine claim on the same building, the church pursued its case, Natural England looked for a licensable route through, researchers found one, and conservationists asked for monitoring. Parliament framed the result as a success, and that is the honest description: the bats kept the roof, the congregation got the church back.
Today St Hilda's is open to visitors, and there are information boards inside telling the story of the bats, which is a gracious touch. A church that could have treated the episode as a grievance instead turned it into interpretation.
Visiting St Hilda's from the village
The best way to see Ellerburn is to leave the car in Thornton-le-Dale and go out on foot or by bike. The beckside and woodland route north from the village is described on the Ellerburn circular walk page, with the wider set of village routes on walks from Thornton-le-Dale. Riders pass the hamlet on the way up towards Dalby Forest; the village-end practicalities, parking, hire and repairs, are on the cycling page, and parking in the village itself is covered under parking.
Please treat it as what it is: a working church in a very quiet hamlet, with a handful of homes and narrow lanes with almost no space to leave a vehicle. Keep voices low near the churchyard, keep dogs on leads, close gates, and remember that services, funerals and private grief happen here. Nothing about a visit needs to announce itself.
This guide does not publish service times or opening hours for St Hilda's, because they cannot be verified here and stale information is worse than none. For current services and access, check A Church Near You (the Church of England's own directory) or the Benefice of Moor and Dale.
If you are making a half-day of it, the tea room at Ellerburn and the village's cafés and pubs are described on eating and drinking, and the wider picture of the parish and its history is on the village page.

Common questions
- Why did St Hilda's Church at Ellerburn close?
- Services inside the church were suspended in August 2011 because bat droppings and urine were soiling the walls, the floors and the altar, which made regular worship inside the building impractical. It followed roughly a thousand years of almost continuous worship on the site, and that year the congregation held their harvest festival outdoors instead. The church reopened in time for Advent and Christmas 2011.
- Are there still bats at St Hilda's, Ellerburn?
- Yes. The church supports a large and important breeding population of Natterer's bats along with at least three other species, and many hundreds of bats continue to roost in the roof space. What changed is that the routes the bats used to reach the body of the church were blocked under licence from Natural England, so the bats keep their roost while the congregation can use the building.
- Is St Hilda's Church at Ellerburn open to visitors?
- The church is open to visitors and has information boards inside that tell the story of the bats. It is a working parish church rather than a museum, so access and service times can change. Check A Church Near You or the Benefice of Moor and Dale for current arrangements before travelling.
- How old is St Hilda's Church at Ellerburn?
- The foundations are thought to be early Saxon, and the structure above ground dates from the 11th century. Ninth and tenth century carved stones are built into the walls, pointing to an earlier church on the site. It was extensively restored in the 15th century and again in 1904 and 1905, with a new lychgate added in 1909. Historic England lists it Grade II*, list entry 1074194, designated on 5 February 1986.
- How do you get to Ellerburn from Thornton-le-Dale?
- Ellerburn is about a mile north of Thornton-le-Dale, in a small valley with Thornton Beck running just south of the church grounds. Most visitors walk out along the beckside and woodland paths from the village, roughly an hour there and back, or ride out by bike on the way towards Dalby Forest. The lanes are narrow and parking in the hamlet is very limited, which is another reason to arrive on foot.
