SU 50 SW TITCHFIELD POSBROOK LANE 23/525 Meon Marsh Sealock and Bridge. II
Former sea lock and bridge. Lock probably C1611 for Henry, second Earl of Southampton; bridge C18; later alterations. Stone, on south west side, lock has retaining walls of coursed squared stone with cyma-moulded coping stones which return a short distance to north-west and south-east, at north-east ends the walls each have a recess (probably from original gate/sluice mechanism). The space between the walls is filled by the inserted C18 bridge which is of crudely-cut stone and has 3 small round arches with roussoirs. A stone pier at north-west side has mason's marks. On the north-east side the retaining walls are of large rubblestones, the north-west side with some coping before, and the space between the walls is filled with sandbags (not of special interest). The lock is believed to have been completed in 1611 as part of the Earl of Southampton's scheme to close the Meon estuary and replace the navigable tidal channel by a canal, which would also drain and irrigate the meadows. It is, therefore, a surviving structure from one of England's earliest canal navigation systems. The canal became redundant within 100 years of its construction and the bridge was inserted subsequently. Archaeological excavation at the southern corner on the north-east side revealed masonry and plan form as on the south-west side, with a mortice for a 2nd sluice gate. It appears that boats collected on either side of the lock awaiting tidal changes and the necessary rise or fall in water levels to enable access to and from the sea.
