Canal passes under flat painted overbridge

Here is "three bridges", built by Isambar Kingdom Brunel, engineer of the Great Western Railway, as part of the contruction of the railway from Southall to Brentford. It was completed in 1859. Brunel died soon adter this, his last work, was completed. Windmill Lane passes over the canal in the same location as the trains rumble beneath. Passenger trains ran on this line until 1942.

Side pont baddles beside lock but brick wall and garden behind

At lock 92, the first of the Hanwell Flight itself, the side ponds have been built over to form a garden for the lock house. The paddles are shown here and the garden is on brick arches.

a large imposing brick wall beside the canal as it stretches ahead

Now the impressive brick wall of the Hanwell Lunatic Asylum comes into view as we move along our tour route. The asylum was opened in 1831. Hanwell became famous for its humane and kind treatment of what were then called inmates. The institution pioneered what was then considered a novel approach to the management of the insane. Previously physical restraints, often of a nature that would today be regarded as cruel, were the normal approach to the control of the mentally ill patient. Dr John Connolly (1794-1866) led the pioneering "non-restraint" system that was adopted by other mental hospitals in England after successful adoption here at Hanwell. The hospital, now part of the National Health Service, provides mental health services to this day.

It is claimed today that canals and their enjoyment are an aid to mental wellbeing. Perhaps Dr. Connolly would have agreed.

A square red door recessed in a thick brick wall

A curiosity in the thick brick wall is the presence of four recessed doors, painted red. These are fire precautions. In the event of the hospital being on fire, the gallant men of the Metropolitan Fire Brigade, (led by Captain Sir Eyre Massey Shaw KCB (17 January 1830 25 August 1908, who is immortilised in the Gilbert and Sullivan Opera Iolanthe) could knock out the doors and run hoses through the small doors to the canal to pump water for fire-fighting. Fire doors in canal walls are not unique to Hanwell, there are examples to be seen in Birmingham and elsewhere. These are amongst the best-preserved examples.

Lock 93 boasts an attractive, single-story cottage

Lock 93 with paddle-gear posts on the lock gate and beside the lock

This is lock 93. Here we can clearly see that there are two white posts on each gate, that support the mechanism for a gate paddle. A gate paddle is an opening in the lock gate itself that allows water to flow from one side of the gate to the other. This is an essential part of the operation of a lock. The water in the lock is raised and lowered - along with it any boat that's in the lock - by emptying or filling the lock. There are also ground paddles in this picture. The ground paddles are installed to open or block a little tunnel that allows water to flow from inside the lock to the canal on the other side, or the other way around. The rack and pinon in this picture are mounted on a wite wooden post.

Beside the canal. two sets of steps lead to an overgrown flat area beside a lock

The picture above is of a landing. It is rather overgrown but lock landings are an important part of the infrastructure. Crew need to re-board boats as they leave locks and the landing is often the place for this, or for disembarkation when approaching a lock.

A large imposing building behind a high brick wall. In the wall is an arch-shaped outline of a bricked-up entrance

As we approach the next lock on this online tour, we come to one of the most interesting remains of the past. A clearly-visible bricked-up entrance can be seen in the wall and behind it is one of the tall buildings of the hospital. This is the former entrance to Asylum Dock. The dock was about 50 feet long and about 30 feet wide and the entrance was at one corner. There were buildings around most of it. Coal was brought in here by barge for the hospital's boilers and produce from the market gardens in the grounds was carried away by boat for sale in the London markets.

This picture at Lock 94 "Asylum Lock" shows the working parts of a paddle that controls water flow to and from a side pond. You can see the paddle itself and the mechanism above to raise and lower it.
