Ingworth Mill was mentioned in Domesday but was shown as half a mill.

Half mills are somewhat common in Norfolk, the profits being divided between two owners and in some cases perhaps between two townships.
Victoria History of Norfolk
N.B. Blickling had 3½ mills

The final mill on the site was constructed almost entirely of white weatherboard with a Norfolk pantile roof and was attached to the mill house.

It was possible several hundred years ago that the river course was altered by digging a new channel nearer to the village in order to improve road communication and also to allow the mill to be built on higher ground slightly away from the natural centre of the flood plain. The older course can be traced as going under the southernmost of the two road bridges at the Aylsham end of the village.

We have been researching Greenacres and have found that a Greenacre was at Ingworth Mill 1676 -1682. He was a William Greenacre and on 28th September 1682 “brought word that his son had run away. And begged that I would release him”. In 1682 Greenacre owed arrears of 35 pounds 18 shillings and tuppence. That in 1682 Greenacre left the mill owing 64 pounds 15 shillings, including a payment in arrears from 1681. Greenacre is shown there from 1676 - 1677.

“19th December 1676 - William Greenacer of Calthorp and William his son, hired the said mill at 34 yearly, delivering eles, fish and capons and upon the same covenants, in the afore mentioned lease or Willis's for 7 years ending March 1684.”

No shine no shade, on they white wall shall fall
Nor rising mists about thee curl and creep
Vainly the breeze may seek, the rough wind call
On the lone river round thee fondly sweep

No sound of splashing wheel or clinking chain
No footpath in the loft or on the stair
Gone the soft crunching of the grinding grain
Only the lonely river weeping there

Good-bye, good-by old mill thy work is done
Like theirs who rest beside thee on the hill
Their labours ended now thine hour is come
No further need for thee old Ingworth Mill

Nay still we see thee in the empty air
Naught can be quite effaced nor good nor ill
And in our visions shall our spirits rear
Pale tender memories of Ingworth Mill

Little seems to be known about the modern history of this mill except that it ceased to work around 1912, it was then dismantled almost board by board. The brick bridge and arches still remain.
