Medieval Rivers

The River Test at Romsey

In the comments section of last week’s post, I had a brief discussion with Doctor Christopher Monk about the use of waterways for transport in the Middle Ages. I wanted to know more, so I did some reading. By the way, if you’re even remotely interested in medieval food, and why wouldn’t you be since you’re reading this blog, you should visit his blog and his YouTube channel.

Rivers were used extensively to transport goods in the Middle Ages. Road transport was dependable and fairly predictable, although slower in winter, but it was expensive.  It cost 1 ½d per mile at the beginning of the fourteenth century to transport a ton of grain. By water it was ½d. It cost more to transport wine 50 miles on land than to send it nearly 1,000 miles from Bordeaux to London. Rivers didn’t go everywhere, though, and often it was easer to transport goods around the coast on ships. Roads were useful if you were transporting people, but if you were moving heavy or bulky goods, like wine, rivers were better.

Many goods didn’t have to travel far from where they were produced to where they were sold. Generally things like vegetables and eggs travelled between 7 and 12 miles, although the shorter distance was the norm. This was as far as the person who had grown it could travel to a market, sell the goods and return home in a day. These people would have travelled on foot, sometimes with and sometimes without a pack horse.

If you wanted your goods to travel further, other people and methods of transport had to be involved. Costs for transporting goods over roads included feeding hungry animals. Most items were carried by pack animals, which needed men to lead them. The animals had to be relieved of their loads each evening and reloaded in the morning, which took time. The same thing applied to carts, which were even more expensive to use, since they were a large capital investment on the part of the owner. Fewer men were needed on boats and no animals. Boats didn’t have to be unloaded and reloaded every few miles. They were another expensive capital investment, but they were cheaper to run than a cart.

Rivers were very useful for bulkier and cheaper goods which would have been prohibitively expensive to transport by road.  London needed to bring in hay to feed its horses and other animals in the winter. The hay was grown in the Lea Valley and transported to London along the River Lea. Had it been transported by road, the cost would probably have been more than the value of the hay.

Most foodstuffs for London travelled by river. Towns upriver from Oxford down and particularly Henley sent grain on the Thames. Vegetables travelled mostly by road, usually from Hertfordshire. Barley came round the coast from Kent and East Anglia.

Medieval boats had more or less flat bottoms and could sail up and down rivers that aren’t navigable for modern boats, although it must be said that some rivers have changed substantially in the last 700 years and some are much more silted up and overgrown than they were. Many rivers were navigable for long distances even for ships and work was often carried out to make rivers as navigable as possible. Channels were sometimes cut where the river was impassable.

Using rivers was not without its hazards. On some rivers there were fish weirs in the deeper water. These were wooden or stone structures built across the width of the river which directed fish into traps from which they could not escape. Not only were they a danger to boats, but they also threatened to reduce drastically the number of fish in a river. This possibility was recognised even in the early twelfth century and there were edicts and statutes against fish weirs over the centuries. That they had to be repeated shows how ineffective they were.  

Low bridges were another danger to boats. Since these were much cheaper to build and maintain than bridges with arches allowing boats to pass beneath them, it must have been a real problem. Eventually lifting bridges were devised. These were bridges with a drawbridge in the middle, which could be lifted for a fee.

Many goods travelled by both road and water, depending on where they were destined. The two methods of transport were complementary rather than in competition with one another.

  1. It must have been nice to travel that way, clean air and water too I should think.

  2. It’s good to stop and think about medieval transport and, in general, the smallness of medieval folk’s world. Very interesting, especially the differences in transport costs. I came across something on this a few years ago when translating parts of the Rochester Priory custumal (13th-century). You’ve made me want to dig it out again. I can’t remember what it said! 😁 Thanks for the shout-out btw. Much appreciated.

  3. I ran the numbers on your stats for perspective: it cost 3 times more to transport goods by land, when you could transport them 20 times farther by water at 1/3 of the cost. Talk about major transportation differences!
