A passage through history

As promised to Don and Cathy Jo, fellow boaters and bloggers, this post is about our trip through and down the historic barge lifts from Houdeng/La Louvière to Strépy Thieu (in Belgium), a distance of some seven kilometres from one end to the other along an old section of the original Canal du Centre. Over its length, there is an overall fall (or rise) of just over 62 metres (217 feet).

To give you some background, I've previously mentioned going up the huge 73-metre lift at Strépy Thieu, a phenomenal engineering feat we experienced on our journey to the Sambre. However, this great lift and its wider cutting replaced four smaller lifts (which I've also mentioned before) that were built between 1888 and 1917, and were designed by Edwin Clark, the engineer who was responsible for the Anderton Lift in the UK. Despite earlier wishes and attempts, we'd never managed to go through these historic lifts on the Hennie H, so when the opportunity arose on our way back to the Netherlands this summer, we simply had to take it. Well, you would, wouldn't you?

I was quite absurdly excited as we approached Ascenseur 1 (Lift 1). Even though we've often travelled to the canal here by car and walked much of its length, I'd never been to this first lift on the system. I don't know what I was expecting, but it wasn't the smart waiting area and new pontoon that we tied up to while we received instructions from the pleasant lock-keeping team member.

Looking at the lift, I was puzzled by its simpler appearance than that of the other lifts on the canal. However, this one had to be repaired and revised some years ago after an accident in which a barge was crushed and stuck in the caisson (the tank that the barges sit in) when the lift started rising while the barge was still exiting. This accident happened in 2002 and during the repairs that began in 2005, a major restoration was performed, probably explaining its somewhat newer appearance.

It was very special for us to be living this history on our own Hennie H. Lift 1 has a drop of just under 16 metres, which is deeper than any of the locks we'd been through. Even more impressive is the fact the mechanisms operating this and all the lifts are original. They work on a hydraulic counterbalancing system in that while one caisson rises, the other descends. What surprised us, though, was how they adjust the balance. If the descending caisson is not heavy enough to lower steadily, water is released from its rising partner. In addition, more water is poured into the descending caisson from the canal above. I have to say this was something of a shock as they didn't warn us, so to see two waterfalls suddenly gushing into our caisson from a dizzy height was not what we were expecting. Nevertheless, it was a simple and highly effective solution, because down we went at a much improved pace.

Increasing the weight of our caisson. This
was later, but the system was the same.

Because it was quite late in the day, we opted to stay the night on the canal and do the other three lifts the following morning. Our obliging lock-keeping team arranged to be ready for us at 10 a.m. and we found ourselves a pleasant spot to spend the night close to the bridge at Houdeng. Our descent of the lift had been in cloudy and slightly rainy weather, but it soon cleared up and we had a lovely evening of golden sunshine, helped by a bottle of plonk from the nearby Aldi supermarket!

The following morning, we set off in good time and headed towards Lift 2, which was around two kilometres further along the canal. What we hadn't taken into account when we booked our passage was the low swing bridge (also a historic monument) about halfway along where we had to wait for the dream team to reach us. They'd probably thought we'd only arrive there at 10 o'clock, so we caught them on the hop a bit.

Lifts 2 and 3 are very close together and both just under 17 metres deep. It was a beautiful morning and I loved being able to see the next lift as we descended Lift 2 in our green duckweed tank. The whole canal surface was covered in weed for long stretches, but it was very thin, so gave us no problems.

And on our way to cover the final few kilometres to Lift 4

The canal to the last lift at Thieu is also quite a stretch. I don't remember exactly how long it is but it must be over three kilometres. There's another pretty historic bridge, this time a lifting one, and our attendant looked on anxiously as we passed through it in case we caught our umbrella on the steel. All was well, though, and we were through for the final leg.

Our umbrella gave the attendant an anxious moment

Another highlight as we made our way towards Lift 4 was looking through the trees and spotting the great Strépy Thieu lift dominating the scenery as it does for miles around. It was a lovely moment of relativity to see it there from our own passage through its historic predecessors. 


The final lift in the stretch was a fitting end to the experience. The view from the caisson is quite breathtaking, looking out as it does over the wide basin at its foot and then further over the golden Wallonian hills on the other side of the new Canal du Centre. What many don't realise is that there is still a further six-metre lock to descend before reaching main waterway, meaning that we were still at quite a height. As a grand finale, the panoramic vista was hard to beat and I was so pleased we'd been able to take this time to 'do' these lifts.

From the old canal to the new. What a sight!

So, Don and Cathy Jo, I hope you (and everyone else) have enjoyed the trip. It was one of the highlights of our travels this year and we were fortunate to be blessed with both the weather and the time to do it. For anyone visiting, there are passenger boats that do tours of all the lifts, as well as two visitors' centres where information about the construction and mechanics of these hydraulic marvels is readily available. We've been to this old stretch of canal by road many times, but nothing can beat experiencing the living history of this waterway by faring through it ourselves.

Have a great weekend allemaal, and I hope the world is kind to you in the coming week.

  1. Val, I think you're very brave with all those locks. I used to take my small boat through locks on the River Thames as a youngster and found it all terrifying. But, you make it just seem exciting and thrilling. I'd love to go through some with you! Doubt that could happen, but at least I went through these ones virtually with you and much enjoyed the ride! Thanks for an interesting blog. Shirley

    1. Thank you, Shirley. I’ll admit there are some locks I don’t like. The 6m one that takes us down to the big canal here is an example. It is difficult to get in and out of, it is unpleasantly deep and narrow, there aren’t enough bollards to tie to and the water rushes in and out too fast. But most of the locks are fine. I loved these lifts. They were a dream come true!

    1. Thank you, Lisette. I hope that one day you’ll have a chance to go on a canal trip. There are some in the US, and also in Canada, so even if you don’t get to Europe, you could still experience them. I’m so pleased you enjoyed our trip, though.

  3. It’s Don and Cathy Jo

    Thanks for the shout outs and letting us see what we missed those years ago. Maybe someday we’ll get back up there someday and be able to follow in your wake.
    Great pics and descriptions!

    1. Glad to be of service, you two. I think you'd enjoy it if you decided to come back to the north. Have you done the big lift and Ronquières?

    2. We did the Thieu lift in 2008 but not the Ronquières. Another one for the “to do” list.

    3. Well, you’ll have to come back then. No doubt. You can come up through the Canal de la Sambre à l’Oise and make that another first 😊

  5. Well, what an adventure you had navigating these lifts. As you mentioned, we have the Anderton Lift in Cheshire but these lifts are on a much bigger scale. I loved reading about your trip and the photo's, thank you.

  8. Val, you and Koos have the patience of Job! You lead such an exciting life while many of us sit behind our laptops. I like the unexpected waterfalls on one lift and the many clear pictures. Gee, thanks, Lynn

    1. Thanks so much, Lynn. We too spend too much time at our laptops but we try and live in the moment as much as possible. I’m glad you enjoyed the post and the pictures xx

  9. I most certainly did enjoy the trip, Val!
    It's odd, because it hardly seems like water travel to me when I see your photos from inside the lifts. So much engineering and machinery involved; very impressive! It must be an unusual sight from being 'on high' and overlooking a pretty view, as you live in such a flat land with most of it being below sea level...
    I loved that you were able to simply moor Hennie H and spend the night basically on the spot, just like that! Your only boundaries being the confines of the canals, of which it seems are easily breached by you and Koos; what is 'plonk', by the way?
    Sending both of you mountains of love, and I look forward to your next installation xx

    1. I always enjoy your comments, Dale. I like the way you look at things from a different perspective. The fact we could moor up on the canal there was a rare luxury. You can't do that everywhere, I'm afraid. Plonk, by the way, is cheap wine.
