Camden Lock is a small part of Camden Town, London Borough of Camden, England, which was formerly a wharf with stables on the Regent's Canal. It is immediately to the north of Hampstead Road Locks, a twin manually operated lock. The twin locks together are "Hampstead Road Lock 1"; each bears a sign so marked. Hawley Lock and Kentish Town Lock are a short distance away to the east; to the west is a long level pound (also known as tract or reach) — it is 27 miles (43 km) to the next lock.

History

Regent's Canal was authorised by an Act of Parliament obtained on 13 July 1812, for a canal from Paddington to Limehouse. When the directors first met, they had decided that all locks would be paired, so that some of the water from a lock emptying could be used to fill the adjacent chamber. Water saving was an important factor, as they knew that water supply would be problematic. Colonel William Congreve, a military engineer who was later knighted, proposed the use of hydropneumatic boat lifts instead of locks. Various designs of a similar nature had been tried in the early nineteenth century, notably at Mells on the Dorset and Somerset Canal and at Tardebigge on the Worcester and Birmingham Canal, but none had proved successful. Congreve's design used two water-filled caissons, which were moved up and down by hand, assisted by compressed air trapped beneath the tanks. With no working examples of such lifts, the directors were understandably cautious, but following an engineer's report, decided that Maudslay & Co should build a prototype at Camden Town. There were a number of technical problems, with the canal company blaming Maudslays for poor design, and Maudslays blaming the canal company for changing the original design and failing to maintain the structure. Congreve's claim that it could be operated in just three minutes was never proved, and in 1818, the directors decided to cut their losses, and reverted to using paired locks. The lift was sold at auction in November 1819, and the 13 lots raised just £404.

Construction of the canal was overseen by architect John Nash, with James Morgan acting as supervising engineer. Hampstead Road Locks were built between 1818 and 1820, with the chambers made of brick and stone coping along the top. The two locks are arranged side by side, with an island platform between them. Each chamber has two gates at both ends, and they have been Grade II listed since 1992 (this is the initial, most common category of listing). They were the first of 12 pairs of similar locks which dropped the level of the canal by 96 feet (29 m) to reach Limehouse Basin. The transfer of water between the chambers made operation of the locks more complex, and so they were permanently manned during the heyday of the canal, with lock-keepers working a shift system to provide 24-hour cover. As the use of the canal declined, in part due to railway competition, manning levels were reduced, and padlocks were used to prevent operation of the locks at the weekends. Following the end of commercial traffic and the growth of leisure boating, the locks reverted to operation by boat crews, and in order to prevent flooding caused by incorrect operation of the paddles, in the 1980s most of the pairs were converted to single locks, by replacing the lower gates of one chamber with a fixed weir. Hampstead Road Lock is the only one where both chambers have been retained, although they are now emptied conventionally. In November 2013, the locks were fully drained for maintenance; the public were invited for the weekend of the 16th and 17th of that month to see the infrastructure for themselves.

The lock is to the west of the Camden High Street road bridge. When the canal was built, the road was carried over it by a brick bridge, but this was found to be inadequate, and was replaced by a cast iron girder bridge in 1878. The cost was met by the St Pancras Vestry and the Metropolitan Board of Works, and the bridge, which has brick abutments with stone coping, carries a plaque recording this fact. Like the lock, it is Grade II listed. At the south-east corner of the lock is a building dating from 1815, which was originally constructed to house air compressors for Congreve's boat lift. It was subsequently used as the lock keeper's cottage, and by 2010 had become a Starbucks coffee shop. The building was extended in 1975, when it was also stuccoed, and a crenellated parapet was added. To the west of the lock is a cast iron roving bridge, dating from the early or mid nineteenth century. It had wrought iron tension stays when built, but these were replaced by steel cables in the late twentieth century, when the deck was also replaced. The towpath is on the northern bank of the canal at this point, and is carried over the entrance to a dock which formed part of Camden Goods Depot by a cast iron single span bridge with stone capped abutments. It was constructed by J Deeley and Co, of Newport in Monmouthshire between 1848 and 1856. The granite setts which form the approach ramps were taken up and relaid in 1978.

Camden Goods Depot

Camden Goods Depot was the London freight terminus of the London and Birmingham Railway, the first inter-city railway to reach London. Robert Stephenson was the engineer in charge of the project, and he picked the site for the goods depot so that direct interchange with the Regent's Canal was available, from where freight could reach the London docks. A 25-acre (10 ha) site on the north bank of the canal was obtained from Lord Southampton in January 1837, and the goods depot was completed in 1839. Major features were a stationary winding engine house, which was used to pull trains up the incline from Euston to Camden, a shed for stabling of locomotives, 18 coke ovens which were used to make smokeless fuel, two goods sheds, stables for 50 horses, a wagon repair shop, and various ancillary buildings. Much of the site was supported on brick vaults. Pickfords, the public carrier, built a warehouse on the south bank of the canal in 1841. It was designed by William Cubitt, was extended in 1846, and was the first rail, road and canal interchange building in Britain, being linked to the goods depot by a wooden railway bridge over the canal.

In 1846, the London and Birmingham Railway merged with several other railway companies to become the London and North Western Railway (LNWR). Just prior to the merger, they decided to build their own interchange facilities, rather than using Pickfords, and this was carried out by the LNWR. Semple's Wharf, on the north bank of the canal, was purchased, and the towpath bridge was built by 1846. A basin and dock were built once the sale of the wharf was completed in 1847, and a new rail link to the goods depot was added. As part of this expansion, two new engine sheds were built, one to the north of the tracks for goods locomotives, and one to the south for passenger locomotives. The southern shed was demolished in 1966, but the northern one, known as the Roundhouse, is Grade II* listed. A second wooden railway bridge crossed the canal to the former Pickfords warehouse.

Following the construction on lines to link to the East India and West India Docks in 1851, which became the North London Railway in 1853, further upgrading of the goods depot was necessary to cope with the volumes of traffic. This took place between 1854 and 1856, and included the enlargement and realignment of the canal basin. When completed, it was 210 by 45 feet (64 by 14 m) with railway tracks on both sides running to the edge of the canal. Four new stable blocks were built next to the Hampstead Road, and the complex was linked to the marshalling yards by the Eastern Horse Tunnel. A Western Horse Tunnel was also built to link the goods depot to new stables near the present Gloucester Avenue, to the west of the mainline tracks. In 1864, the LNWR built a new goods shed, at the time the largest in the country, and in 1876, additional stables were built to the north of Gloucester Avenue. Access to the Western Horse Tunnel was by a set of horse stairs, which have survived. The LNWR good shed was enlarged in 1931, but subsequently demolished. The goods depot closed around 1980, and many of the stables were demolished in 2000. The Interchange Warehouse was remodelled in 1989, to become offices, and further restoration work occurred in 2007, when some of the later additions were removed. It is now known as The Interchange.

Despite some demolition, the complex of buildings, which includes parts of the goods depot, the winding engine house, the Roundhouse, the eastern portal of Primrose Hill railway tunnel, and the canal, represent one of the most important groupings of nineteenth century transport infrastructure to have survived in Britain. The survival of the horse tunnel and stairs shows the importance of horse-drawn transport in the developing railway system.

Camden Lock

Commercial traffic on the Regent's Canal had almost ceased by the late 1960s, and the area had become run down. Much of the industry had moved away, partly as a result of the passing of the Clean Air Act 1956, but also helped by government grants to encourage companies to move away from the city. The area around Hampstead Road Locks was populated by disused warehouses, derelict land and a towpath which desperately needed some repairs to be made. In addition, the area was blighted by the proposed London Motorway Box, which would have seen much of the canal culverted, and a sliproad built over the site of the locks. To the north of the lock was a wharf, owned by British Waterways, but rented out to Dingwall's since 1946. The company made packing cases, but their business had been hit by the change to containers, and in 1971 they decided to sell up. They had about ten years left on a twenty-five year lease.

The lease was bought by Northside Developments, a limited company which had been formed by Bill Fulford and Peter Wheeler, and had previously been involved in turning large houses into flats in south London. Their proposal for the yard was to create workshops, where people worked and sold their produce. They also hoped the development would include a restaurant and cinema. They approached Camden Council, who had wanted to bulldoze the whole area, and persuaded them that some of the heritage assets were worth saving. Northside were advised against including a market in their planning application by the council, and in April 1972 received planning permission for a temporary development, lasting three years, by which time the outcome of the motorway scheme would be known. With such a short lease, funding the scheme had its problems, and several joint companies were created to divide the investment into smaller packets. The plans included workshops, restaurants, sculpture studios, a snack bar, a mooring area for canal boats, and an office. The lease was soon extended to run until 1980, but Northside were refused permission to run a market on Saturdays in the yard and on Commercial Place, the road from which access to the site was gained.

On a very limited budget of £5,000, Northside set about converting the existing buildings into craft workshops. No new buildings were erected, as the whole area was still scheduled for demolition. By mid-1972, parts of the West Yard were ready to be used as workshops, and businesses began to occupy them. An official opening was held on 4 April 1973, with the Mayor of Camden presiding, and this was followed by a three-day display of work by the fifty people who were by then occupying the workshops. Plans for the motorway were dropped soon afterwards. Northside then obtained a development lease, but applications to demolish and replace many of the buildings were successfully resisted by a tenants' association, formed by the craft workers. Newspapers reported the conflicts, and the publicity drew in visitors from a much wider area.

The towpath through the area of Hampstead Road Locks was upgraded and a formal opening was held on 20 May 1972. The next major development was Dingwall's Dance Hall, which occupied the former warehouse used by the packing case company and opened in June 1973. It featured live music, and in order to stay open until 2am, the terms of the licence required an entrance fee to be charged, which was set at 50 pence by the licensing authority. Regular customers included David Hockney, Lucien Freud and George Melly, and it soon became well known as a venue for punk rock bands. Northside next obtained permission to run a Saturday antiques market in January 1974. It would run through the summer months of that year only, with a maximum of 60 stalls, set out in the yard and in a corrugated iron shed. When it opened, there were 12 stallholders, but this soon increased to 30. Better access to the canal towpath was created by knocking a hole in the wall that separated it from the East Yard. The towpath from London Zoo to Camden High Street was then opened for public access, following a campaign by the Regent's Canal Group.

The market was a success, and within a year Northside had obtained permission to extend it to Sundays and Bank Holidays. Soon there were two restaurants on the site, and the range of goods for sale on the stalls became much wider. In the 1976 Conservation Awards run by The Times newspaper and the Royal Institution of Chartered Surveyors, the market came joint third. By the early 1980, the market consisted of nearly 200 stalls, which were occupied by around 100 regular stallholders and many temporary ones. It attracted around 11,000 visitors each weekend. In addition, there were 39 businesses based in the craft workshops. Northside now decided that it was time to change the name of the access road from Commercial Place. The area had been known informally as Camden Lock for some time, and so they campaigned for it to become Camden Lock Place. Despite objections from the fire brigade, the Greater London Council eventually sanctioned the name change, and from then on, the site was marketed as Camden Lock. It became a venue for events, including a five-week Festival of Entertainment, a Clock Festival, and Gerry Cottle's Circus was also booked. British Rail carried out repairs to the railway bridge over Chalk Farm Road in the mid 1980s, and when the work was completed, the hoardings were not replaced. After long negotiations, Northside were granted permission to paint the bridge in 1989, and employed mural artist John Bulley to paint the words Camden Lock in giant letters on the superstructure, together with representations of two painters, painting the letters.
