Discover Garston Lock: A Unique Waterway Feature
Garston Lock is an important part of the Kennet and Avon Canal, a historic waterway that connects the River Kennet and the River Avon. Locks are like water elevators that help boats move up or down between different water levels. Garston Lock raises or lowers boats by about 7 feet and 7 inches (2.31 meters).
The History of Garston Lock
This lock was built a long time ago, between 1718 and 1723. An engineer named John Hore from Newbury oversaw its construction. Today, the part of the river where Garston Lock is located is managed by the Canal & River Trust and is known as the Kennet Navigation.
What Makes Garston Lock Special?
Garston Lock is quite unique because it's one of only two working "turf-sided" locks left on the entire canal. The other one is called Monkey Marsh Lock. Most locks you see are made of brick or stone, but Garston Lock has sloping banks covered in grass and plants instead.
How Turf-Sided Locks Work
Because of its sloping sides, Garston Lock needs more water to operate than regular brick or stone locks. The sloped design means the lock chamber holds a larger volume of water. To help boats stay in the middle as the water level changes, there are special steel rails inside the lock.
Different Gates for Different Jobs
Garston Lock uses two different types of gates to control the water. The gates at the top of the lock work with a mechanical system, meaning they use gears and levers. The gates at the bottom, however, use a hydraulic system, which means they use the power of moving liquid to open and close.
Garston Lock: A Protected Landmark
Garston Lock is not just a working part of the canal; it's also a very important historical site. It's officially listed as a Grade II* listed building. This means it's a building of special national importance and interest.
World War II Defenses at the Lock
You can also find two old "pillboxes" near Garston Lock. These small, strong concrete shelters were built during World War II to defend against tanks. They are located at the northwest and southeast corners of the lock and are also protected as listed buildings.
