Benson Lock
Encyclopedia
Benson Lock is a lock
on the River Thames
in England, close to Benson
, Oxfordshire
but on the opposite bank of the river. The first pound lock here was built by the Thames Navigation Commission
in 1788 and it was replaced by the present masonry lock in 1870. The distance between Benson Lock and Cleeve Lock
downstream is 6.5 miles (10.4 km) - the longest distance between locks on the River Thames.
The weir runs from the lock island level with the lock across to the Benson side. There is a footbridge
over the weir which replaced the ferry
which operated here previously.
can be traced back into the late 14th century when there was a mill at "Bensington". The mill island and stream are on the Benson side downstream of the lock although the mill itself is long gone. There was also a flash lock
, although the first definite reference to this is in 1746. The pound lock was built of oak in 1788 and it is noted that, uniquely for this lock, "Low Country men" were employed at a higher than average wage. Thacker conjectures that these were Dutch specialists. The lock was rebuilt of masonry in 1870. Originally the lock was attended (or not - according to some accounts) by the miller, but there is reference to a (deserted) lock house in 1865. The present lock keeper's house dates from 1913.
and under Shillingford Bridge
. For a great part of the way the two round topped hills of the Wittenham Clumps
are in view. After Shillingford the River Thame
enters the river from the direction of Dorchester
which is a short way to the north.
The Thames Path
, which crosses the river at the lock, follows a road in Benson and rejoins the river, running along the northern/eastern bank to Shillingford. At Shillingford the path follows a diversion through the town, rejoining the river outside the town. It continues on the northern bank, over the River Thame to Little Wittenham Bridge
where it crosses just before Day's Lock.
