A series of 29 locks that raise the Kennet & Avon Canal 237ft over a little more than two miles. The picture shows the 17-lock flight at Caen Hill , where the gradient is 1 in 30.
The canal was built between 1794 and 1816. It runs for 57 miles from the River Avon at Bath to the Kennet Navigation at Newbury, via Devizes and Hungerford. John Rennie was its engineer, his first work of civil engineering in England.
There are many notable engineering features along the course of the canal and at Devizes, the sequence of locks is impressive. Although the locks at Tardebigge on the Worcester & Birmingham Canal are the greatest number of locks in one flight in Britain, at Devizes, the locks rise through a greater height over a lesser distance.
Gas lighting was installed in 1829 to allow movement along the canal at night, for which an extra charge was made.
The locks were closed in 1951, and opened again on 8th August 1990 after major restoration work. A pumping station was built to lift water from the foot of the locks to the top of the Caen flight.
Rennie's resident engineer, John Blackwell, later served as Superintending Engineer for the canal company for 34 years.
