A rather unusual Scheduled Ancient Monument today! Cruising back to Newbury, we pass through Monkey Marsh Turf Lock, outside Thatcham. One of only two remaining on the Kennet & Avon Canal.

Turf locks used to be a common feature in the early days. They were cheap to build, and easy to maintain. However, because they are wider than a brick or masonry lock, they use a lot more water.

On a river navigation, this was not necessarily an issue. All the locks on the River Kennet section of the Kennet & Avon were originally built as turf-sided locks. All but two, however, have been converted to brick.

Being on our narrowboat, I was able to take today’s photograph inside the lock, to give a slightly different perspective. You can see how the sides slope, adding to the width at the top. This is why they use much more water.

Monkey Marsh Turf Lock was originally built in the early 1700s, and is probably due to celebrate its 300th birthday fairly soon! It has a rise of 8′ 8″.
