This shows a famous landmark at Marple in Cheshire where I live. It was completed in 1799 and carries the Peak Forest Canal over the River Goyt. It's the highest masonry-arch aqueduct in Britain.
The boat in the picture is a traditional canal narrow boat (NOT a barge as people often mis-name it) which in its working days would have carried cotton or coal or other merchandise, often with a "butty" boat (or trailor) attached. They were originally pulled by horses but latterly were equipped with engines. Whole families lived on them in very cramped quarters, often supplemented by canvas tenting
The narrow boat in the picture is typical of many others used nowadays on the canal system in Britain as recreational boats either privately owned or hired from holiday companies.
Behind the aqueduct is the viaduct carrying the Manchester to Sheffield railway line, built in the 1860s.
And yes, there is a connection between "my" Marple and Agatha Christie's "Miss Marple". She is said to have passed through Marple on the train and decided on the name on seeing the station nameplate.
