On 27 April 2025, we visited Foxton Locks on the Leicester Line of the Grand Union Canal.
The day began beneath grey skies, with light rain adding a particular atmosphere to the historic brickwork, green slopes and water-filled chambers. It was the kind of weather that makes a canal landscape feel unmistakably English—and certainly did nothing to diminish one of the country’s greatest waterway landmarks.
Our visit came ahead of a significant anniversary celebration. In June 2025, Foxton and Market Harborough would host a festival commemorating 75 years since the influential 1950 Festival of Boats and Arts—not the 75th anniversary of the IWA itself. That original gathering helped demonstrate public support for waterways at a time when much of the network faced decline and possible abandonment. IWA’s anniversary festival details
Walking beside the staircase locks
We began by walking steadily uphill beside Foxton’s famous staircase flight.
The ten locks are arranged as two consecutive staircases of five chambers. Unlike a conventional flight, there are no intervening pounds between the individual chambers: the bottom gate of one lock also forms the top gate of the next.
Together, they lift boats approximately 75 feet over a distance of only a quarter of a mile. Foxton is recognised as the longest staircase flight in Britain and remains one of the most remarkable operational structures on the canal network. Canal & River Trust: Foxton Locks
Watching boats pass through offered a reminder that this is not simply a preserved monument.
Crews opened paddles, handled ropes and moved carefully between the chambers while water flowed through the side ponds. Instructions carried across the flight as visitors gathered to watch—a canal tradition known as gongoozling.
The engineering is ingenious, but its continued operation also depends upon experience, coordination and careful water management. More than two centuries after the locks were constructed, boats still climb and descend the hill using essentially the same principles.
A living piece of industrial heritage
Foxton Locks embodies something particularly compelling about Britain’s canals: their history remains in active use.
The lock flight was built to overcome a substantial change in level on the Leicester Line. Rather than becoming redundant when commercial carrying declined, it survived to serve generations of leisure boaters and visitors.
Today, the site combines working navigation with heritage, wildlife, recreation and tourism. Narrowboats continue to pass through the chambers while walkers, families and volunteers share the towpath alongside them.
That mixture makes the waterways different from many other historic structures. They are not merely exhibits to be viewed from behind a barrier. They remain connected landscapes that must continue working if their full significance is to be preserved.
Discovering the Foxton Canal Museum
At the top of the locks, we visited the Foxton Canal Museum, housed in the former boilerhouse associated with the inclined plane.
The museum helped place the lock flight within the much broader history of Foxton and the inland waterways. Its displays explored working-boat communities, commercial carrying, canal engineering and the later transformation of the network into a place for leisure, nature and public enjoyment.
They also demonstrated how vulnerable the canals once were.
By the middle of the twentieth century, commercial traffic had declined considerably and large parts of the network faced closure or neglect. The survival of so many waterways was not inevitable. It resulted from decades of campaigning, restoration and practical work undertaken by boaters, volunteers, local communities and organisations including the Inland Waterways Association.
The remarkable Foxton Inclined Plane
One of the most fascinating parts of the visit was learning more about the Foxton Inclined Plane.
The staircase locks were effective, but slow passage and heavy water consumption created a commercial constraint. The inclined plane was intended to provide a dramatically faster alternative while also accommodating wider boats that could not use the narrow chambers.
Opened in 1900, it transported boats up and down the hillside inside two water-filled caissons. As one caisson rose, the other descended, using an ingenious counterbalanced system powered from the adjacent boilerhouse.
The structure was an extraordinary example of Victorian ambition. It promised to move boats between the upper and lower levels in a fraction of the time required by the locks.
Its operational life, however, was brief.
The wider commercial improvements needed elsewhere on the route were not completed, limiting the advantages the lift could provide. Operating costs and declining traffic further undermined its viability. It was mothballed after approximately eleven years and later dismantled.
The remains are now protected as a Scheduled Monument. Standing on the site, the scale of the original structure requires some imagination, but the museum’s photographs, models and interpretation help reconstruct what must once have been an extraordinary sight.
Seventy-five years since the 1950 festival
The anniversary being marked in 2025 traced its origins to the Festival of Boats and Arts held at Market Harborough in 1950.
Organised during the early years of the Inland Waterways Association, the event brought boats and supporters together to demonstrate that the canals still had a future. At a time when the network was widely regarded as an obsolete remnant of industrial transport, such gatherings helped build public interest and political support.
The 2025 festival at Foxton and Market Harborough commemorated that influential event with historic and private boats, traders, stalls, music and a boat cavalcade.
Our April visit was not the festival itself, but walking beside the locks ahead of the anniversary provided an opportunity to reflect upon everything the original campaigners were trying to protect.
The importance of campaigning
It is easy to visit a beautiful canal location and assume it has always been secure.
Foxton demonstrates why that assumption would be mistaken.
The locks require continual inspection, maintenance and skilled intervention. Water must be managed, historic structures repaired and public access balanced with the needs of navigation and wildlife. Across the wider network, many canals face growing pressure from ageing infrastructure, reduced funding and changing weather patterns.
The work of protecting the waterways is therefore not complete.
The campaigning that helped save canals during the twentieth century has evolved, but its underlying purpose remains relevant: demonstrating that waterways matter and ensuring decision-makers understand their environmental, social, economic and historic value.
A community built around the waterways
What stayed with us most strongly was the sense of community surrounding Foxton.
Volunteer lock keepers helped boat crews navigate the flight. Museum volunteers shared their knowledge. Walkers paused to watch the boats, families explored the site and conversations began naturally beside the chambers.
Some visitors were experienced boaters; others may have been encountering the canal for the first time. Yet everyone was drawn into the rhythm of the place.
That ability to bring people together is one of the great strengths of the waterways. A canal can be a transport route, heritage asset, wildlife corridor, workplace, home, recreational space and meeting place simultaneously.
Foxton brings all those roles together exceptionally well.
More than nostalgia
Celebrating waterway history should not be confined to looking backwards.
The survival of Foxton Locks matters because the site remains useful and relevant today. It offers access to nature, supports local tourism, provides opportunities for volunteering and enables people to experience industrial heritage through a working navigation.
It also demonstrates what can be achieved when people refuse to accept that an old structure has no modern purpose.
The 1950 festival helped articulate a new future for Britain’s canals. Seventy-five years later, the challenge is to ensure that future remains secure.
That means maintaining navigation, supporting volunteers, protecting heritage and making the waterways accessible to new generations. It also means continuing to explain why these places deserve investment and public support.
A fitting place for reflection
The weather never entirely brightened, but it did not need to.
The rain brought out the colour of the landscape and gave the lock flight a reflective atmosphere. Boats continued moving, water continued passing between chambers and visitors continued gathering to watch.
Foxton Locks provided a powerful reminder that Britain’s waterways survived because people recognised their value and acted before it was too late.
Our visit left us with a deeper appreciation not only for the engineering of the locks and inclined plane, but also for the campaigners and volunteers whose efforts allowed places like Foxton to remain part of everyday life.
Seventy-five years after the landmark 1950 Festival of Boats and Arts, the responsibility passes to another generation.
The setting may be historic, but the task remains firmly contemporary: to protect this living network so that it can continue carrying boats, stories and communities far into the future.
