Monkey Marsh Lock

Monkey Marsh Lock is one of the two remaining "turf-sided" locks on the River Kennet section of the Kennet and Avon Canal.

Using timber and turf for construction, this was an early style of lock-building used on some river navigations. Because of the sloping sides, they use more water than conventional locks, but this is less important on a river. Modern metal posts have been added as a safety feature, to prevent boats from settling on the sloping sides as the lock empties.

Monkey Marsh Lock is near Thatcham Station and about 3 miles east of Newbury in Berkshire.
