What is a Tide Mill
A tide mill is a water mill driven by tidal rise and fall. A dam with a sluice is created across a suitable tidal inlet, or a section of river estuary is made into a reservoir. As the tide comes in, it enters the mill pond through a one-way gate, and this gate closes automatically when the tide begins to fall. When the tide is low enough, the stored water can be released to turn a water wheel.
Tide mills are usually situated in river estuaries, away from the effects of waves but close enough to the sea to have a reasonable tidal range.
Cultures that built such mills have existed since the Middle Ages, and some may date back to the Roman period.
A modern version of a tide mill is the electricity-generating tidal barrage.
Woodbridge Tide Mill
Is still standing and working
The first recording of a tide mill on this site was a medieval mill in 1170; it is unknown how many mills have stood here, but probably three. The mill, which was operated by the local Augustinian priory in the Middle Ages, was acquired by Henry VIII during the Dissolution of the Monasteries in 1536. It is possible that the Augustinians rebuilt the mill shortly before the dissolution. This mill and the former Woodbridge Priory was granted to Thomas Seckford by Elizabeth I. That mill passed through the hands of various private owners until it was rebuilt in the seventeenth century. This is the mill preserved today.
By the outbreak of World War II the mill was one of only a handful still operating. In 1957 it closed as the last commercially operating tide mill in Britain. In 1968 the derelict mill was purchased by Mrs Jean Gardner and a restoration programme was launched. It was opened to the public five years later in 1973. It is now managed by a charitable trust (Woodbridge Tide Mill Trust) staffed by volunteers, and in 2011 the trust undertook a further and more complete restoration and modernization project, including a new water wheel and fully restored machinery, which allowed milling to begin again. It re-opened in 2012 and is now one of only two tide mills in the UK that regularly grinds wheat grain producing wholemeal flour for resale.
