Wortwell mill was built of weatherboard over a brick base with a pantiled roof that also houses the lucum to the front. The mill house is joined to the mill on the southern, Suffolk side of the river and are Grade II listed. The mill ceased working c.1948 and although the waterwheel had gone by 1972, some machinery still remained including the cast iron pit wheel. This was built in two sections on its 10½" diameter cast iron axle that would have also supported the waterwheel, it was 7' 5" in diameter with 8 spokes and 128 wooden teeth. The cast iron wallower had 6 spokes with 54 teeth and was mounted on a 7"-7½" cast iron vertical shaft that also held a wooden pulley with cast iron compass arms that once drove the belt for the tentering gearing. The cast iron bridge trees that supported the stone nuts and the wood great spur wheel also remained. The great spur wheel was made in 5 sections with six cast iron arms and 120 wooden cogs. The wooden crown wheel's wood cogs meshed with two cast iron gears that in turn powered two layshafts, one had a cast iron pulley and also a wooden pulley for the sack hoist and the other had a cast iron pulley. Another pulley was on the outside of the first floor at the front of the mill and was used to take a drive from a portable engine.

In the 1770s the wheel was powering three pairs of stones - one each of Cullens, peak and French burr.
From the early 1900s until c.1932 the mill also ran a small ½ sack roller plant.

Wortwell Mill was usually known as Limbourne Mill and at the time of Domesday a fifth part of the mill was held by Bury Abbey, the whole being worth 10s. The manor of Limbourne in Homersfield was owned by the Benedictine Nunnery of Bungay around 1100. Later there was mention of Limber Lands and Limber Mill within the parish. Many years later these were bought by Alexander Adair of Flixton Hall along with Downs Farm. A conveyance of 1364 included two mills called Lymburghmilles but it is probable that it was the one building with two pairs of stones.

Norfolk Chronicle - 19th October 1782

A Commission of Bankrupt dated 24th September 1825, was announced against Robert Crytoft Harvey, of Alburgh, County of Norfolk, and edward Hill of Wortwell, Said County, Millers and Flour Merchants. Accounts to be audited.

This particular stretch of the Waveney is rich in eels and many were caught below the mill and sent to London hotels and restaurants.

Earlier in the 20th century the mill was owned by the Marriage family.

It was later owned by an artist of the name of Smith before being taken over by Arthur Bush.

Arthur Bush jnr hired the waters by the mill before eventually buying the property in 1949. Arthur was still helping to pull in the eel nets when in his eighties. His father Arthur Bush snr had owned Needham_Mill. When Arthur jnr died in 1973 the mill was sold. The sale particulars stated, Limbourne Mill was the last corn mill on the River Waveney to cease operating on a trading basis. The River Waveney is renowned for silver eel which can be trapped at this point. Arthur Bush maintained traps here for many years and claimed in one year to have caught as many as half a ton in weight of eels.

The mill was auctioned by Apthorpes at the Magpie Hotel in Harleston on 26th September 1973 on the instructions of the executors of the late Arthur Bush. The mill was sold along with the 3 bedroomed mill house and 2½ acres of land.

The mill has a variety of names and dates carved into woodwork throughout the internal structure:
A bracket on the ground floor framing has a carved fleur-de-lis above CS1783 (or 1785) along with RS and the date 178? Another bracket on the ground floor has W+V1783 and E+H97 and a top floor beam has JNURSEY and JB (or JR).

Stanley Clifford-Smith (1906-1968) sold the mill to Arthur Henry Bush jnr. of Magpie Hotel, Harleston before moving to great Bardfield in Essexm where he became an important member of the art community during the 1950s.
