Whitchurch Silk Mill is a watermill on the River Test, located in the town of Whitchurch, Hampshire, England. It is a listed building Grade II*
The mill was constructed in 1800 by Henry Hayter on a plot of land called Frog Island. Some years later, in 1817, it was bought by William Madick who changed its operation to throw silk. In 1844 it was acquired by Alexander Bannerman and John Spencer, merchants of Manchester. William Chappell, the manager of the mill, purchased it from them in 1846. At this time the mill employed 108 staff, including 39 children under the age of 13. By 1866 the mill had passed into the ownership of the Hide family with whom it remained until the death of James Hide in 1955. During this time, the mill wove silk for Burberry, then based in nearby Basingstoke, who used it as coloured linings for their raincoats. It ultimately passed to Ede and Ravenscroft who operated it up to 1985, producing legal and academic gowns. It was then acquired by the Hampshire Buildings Preservation Trust who, after renovation works, opened it to the public in 1990.
In December 2012, the Trustees recommenced silk production. Whitchurch Silk Mill Trust weaves silk on Victorian machinery in the Georgian watermill of Whitchurch Silk Mill, Hampshire. The mill is open to the public who come from across the UK and abroad. The charity educates visitors about silk, retains and develops the skills of silk weaving and restores its historic machinery.
