NHER 5931 (Monument record) - Former Bishop's Mill or St Audrey's Mill and site of early cloth mill

Site of mill.
Information from (S1).
R. R. Clarke (NCM).

A mill is marked on Faden's 1797 map (S2). It's marked as a Paper Mill on the 1st edition 1in Ordnance Survey 1838 (S3) and some sort of building is still present on the site on the 1975 Ordnance Survey 1:25000 (S4).
An article by D. Stoker (S5) states that the first reference to a paper mill in Thetford was in 1753, when William Holmes insured his goods and stock. Correspondence from 1785 states that the Thetford mill was the only one 'in this part of the world' producing white instead of brown paper, but this is likely incorrect as a directory of the book trade from the same year lists both Thetford and Stoke Holy Cross as producers of white paper.
Mentioned as Bishop's Mill as late as 1865.

Early Cloth Mill
This is the site of one of the three mills in Thetford mentioned in Domesday. Throughout the early medieval period it was owned by the Abbot of Ely and produced cloth. Blomefield (S8) describes it as a 12th century fulling mill, but it likely did not carry out this process until slightly later. The mill continued to produce cloth and possibly corn until the 17th century.

17th century: Paper Mill
The mill was converted to produce paper in the 17th century. In the 18th and 19th century it was known as Bishop's Mill or St Audrey's Mill. Paper production continued throughout the 18th century when it was owned by William Holmes and in the first decade of the 19th century it was enlarged, covering 3.5-4 acres and incorporating the land previously known as Small Bridges Common. In 1869 the mill began to carry out hat-felting and from 1873 to 1879 hats, paper and pulp products were produced here by the Charles Vickers and Co. (later Vickers and Knowles). See NHER 51706 for information on pulp ware and the Thetford Patent Pulp Manufacturing Co.
See (S6) and (S7) for further details.

1879. Establishment of the Thetford Patent Pulp Manufacturing Co. (see also NHER 51706)
The Thetford Patent Pulp Manufacturing Co. was established here in 1879 (see NHER 51706) in what at that time was said to be a fulling mill, converted to paper making. In 1875 Vickers and Knowles had tried unsuccessfully to make pulp hats here. Pulp ware was then made by steam engine as well as water. The mill burnt in 1897 and was rebuilt and enlarged. At this time a Gilkes 30hp water turbine was installed, which worked until about 1958 when Paxman diesels were inserted. By this time the mill building itself had gone out of use. The last true pulp ware was produced in the 1950's, but by this time the company had already begun to switch to plastics and fibregalss for making injection-moulded products (see NHER 51706).

1961. Change of name to Thetford Moulded Products.
The Thetford Patent Pulp Manufacturing Co. changed its name to Thetford Moulded Products in 1961 when it complety converted to the production of plastics. Although no longer in use, the mill building remained under the care of Thetford Moulded Products (later Centurion Safety Products) until 1990, when the company moved its premises to Howlett Way.

Excavation of three trial trenches in the area south of the river recorded the foundations of a late medieval to post medieval structure which may have been associated with the mill or other river activity.
