Constructed 1796-1801 to carry the Leeds and Liverpool canal across the calder valley, this was the largest canal embankment in Britain
Yorkshire St, Burnley BB11 3BN
The Burnley Embankment - known locally as "The Straight Mile" - carries The Leeds and Liverpool Canal 60ft above the town.
It was built between 1796 and 1801. Though costly to construct, it meant the valley could be traversed by the canal without the need for two systems of locks.
The embankment, an innovative solution to the problems of canal engineering in its time, remains an impressive construction today. It is widely regarded as one of the "seven wonders" of the British Waterway System.
