Sprowston postmill has one of the best documented mill histories in the county and has been the subject of several books. It was built in 1780 and was destroyed by an accidental fire on Friday 24th March 1933. It was sometimes known as Mousehold Mill.

The main post of the mill was 32” square at the base and the collar had a ball bearing arrangement, with 40 2¼” diameter cast iron balls. The mill needed about two tons of grain in the tail to balance the machinery in the head. The fantail took 625 revolutions to turn the mill through 360º and the sack hoist was driven by a cone clutch from the brake wheel.


The mill was originally built as an open trestle mill without a roundhouse and in that state was the subject of an etching by John Crome in 1810 that went on to hang in the National Gallery. The etching showed Sprowston postmill and Bond's mill together.

The mill was first shown on Faden's map of 1797. Thomas Carlton is given as the miller at Sprowston in the 1817 Poll Book and he advertised the mill for sale in 1823.

Robert Robertson was the miller by 1824. He had the patent sails and fantail put on the mill. He had married Sarah Rockhill in 1820 and may have been at the Market Hills post mill in Great Yarmouth from 1820 to 1822. In 1824 a daughter Julianne, was born, then in 1827 another daughter, Susannah and in 1830 a son, George Rockhill. Robert Robinson was listed in Pigot’s Directory of 1830. In 1831 he had another daughter, Hannah Rachel. On the 19th July 1832 there was an accident involving his horse and cart.

On the 19th July 1832 there was an accident involving Robert Robinson's horse and cart.

We have this week to record another very serious accident arising from a horse running away with a cart. It appears that on Monday evening a valuable mare and cart belonging to Mr. Robinson, miller, of Sprowston, was standing at a baker’s door, in Ber-street, and during the absence of the man, who was collecting empty sacks, the reins became entangled with the tail of the mare, and she set off down Ber-street, along Goldenball-lane, and at full speed down Castle Ditches, as far as the New Shirehall, whence she was met by a poney and gig, in which Mr. J. Muskett, of the Yarmouth Bridge Inn, and Mrs Bailey Bird, relict of the late Mr. Bailey Bird, of Red Lion-street, were returning from a ride. – So frightful and tremendous was the collision that the shaft of the gig entered just beyond the shoulder of the mare, and penetrated the heart, and she fell lifeless on the spot. At the same time Mr. Muskett and Mrs. Bird were thrown out with great violence; they were soon conveyed home, and surgical assistance sent for, when it was found that Mr. Muskett had received a severe fracture on the head, and his body was much bruised, and that Mrs. Bird had one of her arms broken, and was otherwise very seriously injured in the head. The poney was cut across the eye and the gig damaged. We regret to say that Mrs. Bird died yesterday (Friday) noon from the effects of this dreadful accident, and that Mr. Muskett’s death from the same is hourly apprehended.
Norfolk Chronicle - 25th July 1832

Mr. Muskett died on the 30th August 1832

In 1834 Robert Robinson had a son, William Alfred.

Saturday night last, some person or persons broke into the mill of Mr. Robertson, of Sprowston, and stole therefrom 25 stone of flour and two sacks.

Robert Robertson was listed in Pigot's directory of 1839 and Blyth’s Directory of 1842. He was killed in an accident in the mill on the 8th March 1842.


Tuesday last, aged 48, Mr. Robert Robertson, miller, of Sprowston from a fatal accident in his own mill. His loss in all the relations of life as a husband, father, and friend, will be deeply mourned by his bereaved family: and sincerely felt by the neighbourhood in which he lived, where he was a pattern of that pious conversation and upright conduct which true religion alone inspires.

An inquest was held on the body or Mr. Robert Robertson, miller, on Tuesday evening, before Mr. Pilgrim, at the Norwich and Norfolk Arms, Sprowston, when the Jury found a verdict of “Accidental Death.” It appears that as the deceased was putting the strap into the bolting mill, he was caught up by the wrist and was drawn up till he stuck fast at the shoulders in the machinery, the body of the unfortunate man stopping the mill, which had been observed to stand still for a quarter of an hour. When found, he was dead. He leaves a widow and six children to lament the catastrophe, which has deprived them of the best of husbands and fathers.
Norfolk Chronicle - 12th April 1842

The above account of Robert Robertson’s death contradicts the version in H. C. Harrison’s book that he became entangled in the drive from the brake wheel to the sack hoist. He was buried in Sprowston church. The ownership of the mill then passed to his wife, Sarah Robertson.

To Millers and Bakers.

A CAPITAL WINDMILL driving two pairs of STONES, situate near one of the most populous parts of the suburbs of Norwich, and in which a good Trade has been carried on for many years.
For Rent and further Particulars apply to Mr. Thomas Rackham, King-street, Norwich.

George Rockhill Robertson died in 1884.

The mortal remains of the late Mr. G. R. Robertson, miller and Merchant, of Sprowston, Norfolk, were laid to rest on Monday May 5 in the churchyard of that parish, and in the presence of a large assemblage of mourning friends. The deceased gentleman had succeeded his father in the occupation of the Sprowston Mill, and had earned the esteem and regard of his neighbours.

William Albert Harrison inherited the mill from George Rockhill Robertson, who was his maternal uncle. It was his mother, Elizabeth Sarah, eldest daughter of Robert Robertson, who had found her father dead in the mill. She died c.1915, aged 95.

c.1928 c.1926

William Albert Harrison’s wife was Rachel Margaret. In 1885 they had a daughter, Edith Alice; in 1886 they had a son, William Edmund; in 1888 they had a son, Herbert Clifford; in 1891 they had a son, Horace George; in 1893 the had a son, Leonard Linford and in 1897 they had a daughter, Olive Victoria.

William Robertson of Stratton_St Michael_postmill, was the eldest son of William Robertson and Elizabeth Scarffe of Hethersett.
William jnr's brother George took over the running of Hethersett Gt Melton Road postmill in 1829.
Robert Robertson took over at Market Hill mill in Yarmouth before moving to Sprowston.
Abraham Robertson took over the lease of Deopham smockmill on 18th September 1826.
Elizabeth Robertson married John Hastings who was running Starston postmill in 1854.
Susan Robertson married George Willis, a miller & baker from Mendelsham, Suffolk .
John, Simon, David and Samuel Robertson do not appear to have become millers.

John Robertson's son George Wilby Robertson worked in one of the Upper Hellesdon and one of the Gayton windmills. Robert's Robertson's oldest daughter, Elizabeth, married a Harrison of Sprowston postmill.
Elizabeth's sons worked Oulton Broad, Gisleham, Wangford and Sprowston mills. Her oldest son Robert William helped at Sprowston postmill after his father was crushed to death and he later bought a mill at Oulton Broad. Her next son, George, continued the family line at Sprowston and her youngest son, William Alfred, was an apprentice at a Wymondham mill and a journeyman at Great Bentley, Essex and he later owned St Margaret's Church Mill in Lowestoft.
Abraham's son Wiliam Proctor Robertson worked a mill in Eaton.

c.1927 1927


Horace George Harrison, who followed his father at the mill, used to say that he remembered the great gale of Sunday, 24th March 1895, which rocked the mill. His father turned his back on the mill saying he did not want to see it fall. However, it survived with little damage. In 1920 Horace G. Harrison hired the mill from his father. He was listed in Kelly’s Directory of 1924 as a miller (wind) Windmill Road, living at 481 Sprowston Road. By 1928 it was no longer economic to keep the mill working and it reverted to William A. Harrison.

In 1933 arrangements had been made to hand the mill over to the Norfolk Archaeological Society for preservation by a Trust, as from 25th March. However, on the 23rd March someone lit a rubbish fire at the edge of Mousehold Heath, the gorse caught fire and flaming debris blowing onto the canvas sails soon set the mill alight.

Horace G. Harrison took the nearby “Brickmakers Arms” when he left the mill in 1928. After war service in the Royal Air Force he eventually retired to Shipdham, where he died on the 29th November 1976, aged 85.

For about fifteen years, the late Mr. H. O. Clark worked on making an exact scale model of the mill at a scale of 1” to 1’, which is now in the Science Museum, London. It had long been thought, and he was of the opinion, that this was the windmill depicted in John Crome’s painting of a windmill near Norwich, now in the Tate Gallery, London. However, consideration of other details in the picture, particularly the chalk pit in the foreground and comparison with similar pictures now supports the view that John Crome’s painting represents Trowse open trestle post mill. In fact, the frame of this picture is said to bear a label to the effect that it is Trowse postmill.

I have just inherited from my late mother a wooden bowl, about 18 cms. in diameter, and fitted with a small round brass plate bearing an  engraving of the mill and inscribed "Oak from  Crome's Sprowston Mill  - 1780 -1933".
I believe the bowl came from my mother's father, Mr. Sam Sleigh, a  journalist on the East Anglian Daily Times, who acquired it soon  after the mill's destruction.

Steve Wood - 3rd February 2010

I have just visited your website, having been told of its existence by a newly found English distant cousin (a Robertson).
I was particularly interested in your section on Sprowston postmill as I am a granddaughter of the late Herbert Clifford Harrison who was born in the Mill House in 1888 and wrote two books about it. I have known about the mill all my life (my grandfather died in 1962 when I was 9, and his wife Nora and son Hubert (my father) both died in 1997, aged 99 and 75 respectively). I will be traveling to England in September so intend visiting the site of the Mill and Mill House (both now long gone of course).
I was also interested in the last note added by Steve Wood a few weeks ago re the wooden bowl. I too have a wedge-shaped piece of oak from the mill with the same brass plate. I am not certain exactly what the item is (about 17cm by 11cm), but it was obviously meant to sit on a desk (its bottom surface is covered with green baize), perhaps as a paperweight, and has two nails protruding from the front, presumably to suspend a picture or small calendar or something. I think it's lovely that although the Mill itself has been lost long ago, small pieces of it remain scattered across the globe!

Several years ago I was fitting central heating in my house and found that sometimes I could drill my wall to fix things to easily and then another time it was almost impossible to drill at all. I am talking way back some forty years ago, when electric drills did not have a hammer action to aid the drilling of hard material. Any way I mentioned this to a man who lived opposite to me in Russell Ave. Sprowston, and he said it was because my house was built using bricks recycled from the burnt out mill on the heath.
To verify this I went into the roof space of my house and could see the mixture of assorted bricks. Some soft Norfolk reds and others very hard cream ones.
