where is the haywain by john constable
Following the fashion for painting mountainous, Romantic scenery, he spent some time in Derbyshire (1801) and the Lake District (1806), but it was only on his return to the quieter, less spectacular countryside of his native Suffolk that he developed his personal style. From 1810 there is an uninterrupted series of drawings and oil sketches painted in the open air and depicting his native countryside in what was an unusually fresh and direct manner.
In the 18th century there had been a gulf between, on the one hand accurate topographical views, for example those of Paul Sandby, and Romantic or expressive landscape epitomised by J R Cozens. It was Constable’s achievement to combine these two tendencies: he portrayed his native Suffolk and one or two other areas in a manner both more naturalistic than that of any of his predecessors and yet imbued with a deeply Romantic spirit.
John Constable and JMW Turner are the two finest artists of their era and were also fundamental to promoting landscape painting as well as British art in general which previously has been overshadowed by painters from Northern European countries such as Germany and the Netherlands, plus of course Italy who inspired the Renaissance.
John Constable played a crucial role in the rise of landscape painting as an accepted art form within the mainstream and it’s easy to take his career for granted with so many landscape artists now around.
The Hay Wain was voted the second most popular painting in any British gallery, second only to Turner’s Fighting Temeraire, in a 2005 poll organised by BBC Radio 4’s Today programme.  On 28 June 2013 a protester, reported to be connected with Fathers 4 Justice, glued a photograph of a young boy to the painting while it was on display at the National Gallery. The work was not permanently damaged. 
Painted in oils on canvas, the work depicts as its central feature three horses pulling what in fact appears to be a wood wain or large farm wagon across the river. Willy Lott’s Cottage, also the subject of an eponymous painting by Constable, is visible on the far left. The scene takes place near Flatford Mill in Suffolk, though since the Stour forms the border of two counties, the left bank is in Suffolk and the landscape on the right bank is in Essex.
On the right a fisherman, half concealed by a bush, stands near his punt while a duck glides by. The ripple and movement of the water is finely indicated, as are the masses of white cloud drifting across the sky, and the darker ones on the left, a sign of an approaching shower.
For seven years they remained loyal to each other and were on the verge of eloping when John’s father’s death in 1816 left him financially secure and they could at last marry. Even then, none of her family attended the wedding.
However idyllic Constable’s view of rural England was throughout his career it’s unlikely that there was as much calm and happiness in the countryside during this period. Due to the onset of the Industrial Revolution in the 19th century, many rural people found themselves out of jobs as farming work became more industrialized and machines reduced the man power needed to harvest and maintain crops and animals. Large areas of Britain also saw uprisings and riots amongst the rural communities that were affected by the job losses.
Although Constable is famous for being one of the first landscape painters to create canvases purely based on nature, he did not paint The Hay Wain on site. Instead he created several sketches in the summer of 1821 and produced the finished oil version in his London studio in the winter of the same year.
