Sonning Lock

Sonning Lock is a lock on the River Thames in Berkshire with a large wooden gate system that controls water levels. The structure allows boats to navigate the river's elevation changes and serves as an important point along the waterway.

The first lock at this location was built in 1773 by the Thames Navigation Commission. A rebuild took place in 1787 when oak wood replaced the original fir in the structure.

The name "Sonning" reflects the area's old English roots. Today, the place is known for its peaceful riverside setting where visitors can watch the rhythm of water life and boat traffic.

Access to the lock is available from the riverside path and the area is well laid out for walkers. Visitors should know that operating conditions are influenced by the river's water flow throughout the year.

James Sadler, the lock-keeper from 1845 to 1878, wrote a detailed guide about the Thames that preserved many observations from daily river life. His records offer visitors a window into how someone living at the lock saw the water and its changes.
