Marlow Lock

Marlow Lock is a structure on the River Thames that manages water levels to allow boats to travel between different elevations on the river. The installation includes gates and chambers that control the flow of water through this section of the waterway.

A weir existed at this location in medieval times, but the current lock was built in 1773 by the Thames Navigation Commission to improve navigation. This early installation was pioneering technology for managing water flow on the river.

The area drew writers and poets during the early 1800s who sought inspiration from the riverside location and its quiet setting. The lock remains connected to this literary past through the memories of those who stayed along this stretch of the Thames.

The best approach is to walk from Marlow town center since no dedicated parking exists at the lock. The area is flat and straightforward to explore on foot, with clear signs pointing toward the structure.

Between the lock and the old weir sits Lock Island, home to private residences that are only accessible by footbridge or directly from the river. This small enclave remains hidden from most visitors, creating an unusual living arrangement in the middle of the waterway.
