La Loire Vivante - Part 1

Around Saumur

We arrived in Saumur around 11:00am on Saturday 2nd May, two unseasoned Brits abroad speaking very bad French, worse for our estuary English accents. We were disorientated and punch drunk after an overnight ferry crossing with patchy sleep and a much earlier start than we’re used to for the drive south from Ouistreham. Leaving the autoroutes and coming to Saumur from the north, we crossed the Pont des Cadets de Saumur and came to a broad but busy street, though this wasn’t the main town. We were on the the Île de Millocheau, one of the numerous islands in the Loire. We then, though came to the main river channel, the wider one, crossed via the Pont Cessart to the main town, built beneath a ridge of limestone. After a smooth, blissfully quiet journey along the autoroutes during the early morning, the busy streets and traffic were a shock on the system. It was market day, with stalls in the main square and the road from the bridge closed to traffic. We grabbed a coffee and galette in a café in the Place St. Pierre then had a wander around the town, before the rain really set in. Much of it appeared to be a building site: both the chateau at the top of the hill and the Eglise St. Pierre in the square of the same name.


I’d first met the Loire on a summer camping holiday over thirty years ago, based at St.Aignan-sur-Cher to the south of Tours. Back then we were both been very different: the Loire was fairly low as it tends to be towards the end of the summer, its channel strewn with large sandbanks. I was a teenager, a life stage I’m glad I won’t have to repeat. I wasn’t cool at school. Instead, I was into rivers. That year (1982), I’d been lucky to have two trips to France visiting two its grands fleuves (main rivers). During the Easter holiday I’d seen the Seine on a school trip to Paris. For various reasons - including needing a liver transplant in my early twenties – I’d hadn’t got round to revisiting the Loire until now.

After another relatively dry and mild spring and late winter in southern England, I was worried it might be running a bit low. Instead, when we got to the riverside at the Pont Cessart, we found it filling its 500m wide channel (approximate width of the two channels either side of the island combined), brown and very turbid and running with a powerful current. Though I’ve seen faster currents elsewhere – certainly the tidal Severn and in continental Europe der Inn tanked up with Alpine glacial water – it was the force of the water. This was particularly noticeable on downstream side of Pont Cessart, built with multiple arches / pillars many of the stone bridges along the Loire tend to be . It wasn’t just the middle of the river (usually the fastest bit) but the full width of it. Admittedly, it had been a while since I’d seen a river this size or upwards. Below Tours it’s typically 500m wide, plus various islands large enough to build a good size village on. At just over 1000km (1006 km / 625 miles) it’s the longest river in France, about three times the length of the Severn or Thames. It’s basin has a surface area of more than 100,000km2, a fifth of France and its annual mean discharge at its outlet at St. Nazaire is more than 900m3s-1. The equivalent figures for the Thames (London) are around 13,000km2 and around 65m3s-1 (figures from Wikipedia).

What I hadn’t factored was spring snow melt in the mountainous Massif Central, where the Loire rises. Its regime is pluvio-nival océanique (according to Wikipedia France), ie its flow is fed predominantly by rain bearing north Atlantic weather systems, like Britain’s rivers, but there’s also a significant contribution from mountain snow melt. 

Usually in a car, (as we found on our way down here), signs labelling rivers at bridges are pretty pointless as there’s seldom much of a view.  All the more on motorways and dual carriageways and even on narrower roads, the view’s invariably hidden by the wall of the bridge. The Loire was far too wide to miss but these signs at bridges over French rivers say whether it’s a “girl or a boy”. In French all nouns are masculine (le for the) or feminine (la). I don’t know what determines the sex of rivers / who decided or where or when – rivers running off the Alps tend to be powerful and robust - le Rhone, le Rhin (Rhine), der Inn (German masculine) – but it’s la Loire is feminine. Confusingly, la Sarthe has le Loir as a tributary. We crossed both of them on the autoroute south of le Mans.

By the middle of the afternoon, the rain was really setting in. We retreated to the car, following the road running along the beefy 10m high floodbank (levée) protecting the town, passing Careful Where You Park…type signs for the parking areas on the quay beneath it:

Secteur Inondable - Submersing Area Danger

On another nearby wall was a trilingual No swimming sign.  The German Achtung Schwimmen verboten tends to grab people’s attention when spoken, or maybe even the French Attention Baignade interdite. The English – Careful – was whimpish in comparison.

We were parked at the LeClerc supermarket-cum-shopping Mall (another place we couldn’t quite get our heads round given the punch-drunk state we were in), situated alongside Saumur’s “junior river”, Le Thouet. Junior to La Loire maybe, but it’s about the same length as the Tewkesbury Avon, one of the larger rivers in England. Though it flows northwards as far as Saumur, it then “has to” take a left turn about 2 km before it can join the Loire at Bouche Thouet. In comparison to its more senior partner, it was appeared to be a quiet, unassuming river and not unduly high. It’s regime is purely pluvial.

There was plenty of this (rain) throughout the rest of the day, overnight and into Sunday morning. We knew it was coming: the anticyclone that had been with us for much of April, like us, decided to go on holiday. A low pressure, tracking further south than had been typical for the year so far, filled the gap. Though not particularly deep, it had lengthy rain bearing fronts stretching at least as far south as central France. Once it had passed through, the weather during our week in the Loire valley remained unsettled, though not as wet as on our arrival. We sat out the worst of Saturday's lot in the car – we needed to take time to dose and chill out anyway – before undertaking a somewhat dazed and confused supermarket shop, before turning up at the holiday cottage to the north of the town. 


-------------------------------------------------------------------------



We had a much quieter (and drier) stroll around Saumur on the Sunday afternoon, beginning along the Avenue du Marechal Foch, passing the École de Cavalerie (photo right) on our right and La Distillerie Combier a bit further along. We then walked up to the château from the Place St. Pierre. Here we strolled along along the ramparts and admired the views over the river and the town. However, the chateau itself was closed for essential longterm renovation. Much of the building was clad scaffolding. Photo opportunies restricted here then. When we returned to the public garden near the small vineyard on the east side, I focused on the view down to the river, though still had to use some artistic license for the building when I sketched the view down to the river. I also did some quick sketches here before our stroll along the ridge on Sunday: looking westwards along the Loire to the Pont Cessart and the Pont du Cadre Noir beyond it. The latter was a plainer, more modern design carrying a fast, busy dual carriageway linking with the autoroutes. In the view eastwards towards the railway bridge, I indicated strong currents and ominous clouds. Actually, the sky was beginning to clear, though it remained warm and humid and we felt a bit too hot when the sun came out later in the afternoon.

The Château was built on the Butte des Moulins – there used to be lots of windmills here; still evident in the names of some the houses we passed as we began walking westwards along the ridge. As with all the hills in the area, it was composed to tuffeau. This is a form of chalk, the same age as the chalk in the rest of the Paris Basin and, indeed the chalk we have in England, late Cretaceous, c 90Ma.  Though, it all formed in much the same way, is much tougher and the colour is yellower. It is strong enough both for use as a building stone in the châteaux, churches and to support the distinctive cave networks / trogolodytes cut into the hillsides  along the Loire. with f and other buildings along the Loire. and easily carved into blocks. However, all limestones chemically weather in mildly acidic rainwater. From what we saw during the course of our week, it looked particularly susceptible. 

Though it had a long way to go before reaching the point of débordement (overflowing out of bank), and it was still well down in the levêes, the Loire had indeed risen in response to the rain and overnight. This was most noticeable on the north side of the Île de Millocheau, the full width of the channel here now submerged. Though it was a modest rise, this river still seemed to respond quickly - I thought bigger ones took longer (though see later notes about its notorious flood history). It rose a bit more during Monday and probably peaked during the middle of the week after inputs from tributaries such the Vienne, though the rise was slower and less obvious. It didn't quite spill onto the onto the quay, meaning my worries about parking there turned out to be unwarranted. As far as I know (Vigicrues) there weren't any flood alerts or warnings along the Loire, though there were a couple of alertes jaunes - We don't expect things to get serious, but Watch Out (probably equivalent to the Environment's Agency's Flood Alert in England and Wales. I later found out (France 3, website, 5th May), though that there had been flooding along the Indre and in the grounds of the Chateau at Chambord, on le Cosson to the east of Tours. It was as well weren't in that area this time. 

View across the river to the Île de Millocheau. At the eastern tip, a campsite. We couldn’t see whether the or not the Loire had spilled among the greenery here, though this end of the island looked particularly low lying and more exposed.

We then walked eastwards along the ridge, roughly following a section of the GR3 route along the lane at the top. Several house names pertained to windmills, such as Moulin Solaire. The road then opened out into farming country, with another vineyard. Though no windmills, two water towers. As seen with the Cargate Water Tower (see notes in April), most water towers in the UK have been torn down now. In France, they are still common. Presumably, they are to serve farms. A man with a laden donkey passed us along the lane.

When we got to the farm buildings and were roughly level with the railway bridge, We followed narrow and paths steeply down the hill to the river, following the Loire back to the Pont Cessart. We came down near the railway bridge, where there was a small park. Solo angler and dogwalkers. A St. Bernard. Upstream of the island here, it was a bit wider, the current not quite so strong. Despite the current, a pleasure boat. Though the Loire is officially navigable for the last 35 miles downstream from Nantes, where it is tidal, but that’s for modern shipping, requiring deeper water. Until the late nineteenth century, however, it was a major trading route. Strong currents, the very varied flow regime with a tendency to both drought and flood, navigation on the Loire was always difficult. Today, for its size, it’s remarkably free of boats, though there are now pleasure boats like this one, making considerably faster progress with the current than against it.

To our left along the road by the river was the tuffeau cliff in the hill, with a trogolodyte dwellings. A sign to the tank museum. Church / cathedral with large dome. This was the Notre Dame des Ardilliers.

Trogodytes, modern cave-based food cultivation and art studios

After spending the Monday morning in Saumur, we headed westwards across the Thouet to sample some of the underground culture along the Loire, at the Musee du Champignon.  This was set in a network of caves cut into the tuffeau hillside. We were able to buy a combined ticket for this and The Pierre et Lumiere (€13),  which was 300m westwards along the road. apart. Both museums were set in cave systems going well back into the hillside. The mushroom museum was particularly extensive. Both educational and also a working site, mushrooms cultivated in the cave systems to sell to shops / restuarants in Paris and well beyond. The biggest mushroom producer in France. These caves are great for cultivating mushrooms as they stay at a fairly constant temperature and high humidity through the year. Displays in French and English. In the two main displays: the myriad of mushroom varieties from all over the world, all shapes, colours and sizes, edible and toxic mushrooms (not always easy to tell the difference). Furthest back in the cave was La Champignonniere, where they cultivate mushroom. Not only in beds of soil / compost on the ground, but also in more unsual ways – grow-bags, some hanging “nougat” slabs of soil with mushrooms growing out from the sides.

Just ahead of a big coach party of French youngsters, we headed 300m westwards to the next one, the Pierre et Lumiere.

Pierre et Lumiere - Stone and Light

Here there was stone sculpture of various landmarks along the Loire and riverside towns, mainly carved in situ from the tuffeau. All viewed via a one way system through the cave network, moving up the Loire from west to east, beginning west of Angers and ending east of Tours at Amboise. It could have been twee, but wasn’t. Intricate carving involving tonnes of tuffeau, one 40 tonnes. All tastefully lit. The sculptor was Philippe Comander. Noted he started out in Brittany, carving granite, which would have been much tougher / literally harder than tuffeau. It gave us ideas for places to visit during the week. Chinon and Candes St. Martin were a must. Other highlight sculptures were: Angers – riverside view (from the Maine), ochre tint of water and sky added constrast enhancing the overall effect. Chateau and buildings. Use of Anjou slate in the chateau walls (ardoise). Angers is about where the Loire enters the harder, metamorphic / igneous terrain of the Amorican Massif. Saumur – view from a cross the Loire, plied by a sailing barge.Sculptor had to work in 95% humidity to create this. The cathedral at Tours, with its twin spires on the west front. Changing colour backlighting.  Intricate carving of stained glass windows etc.

Troglodytes dwellings along the Loire valley have various uses, among them homes, eateries, wine storage, also art studios. I'm not a sculptor and painters usually seek plenty of natural light. However, the cool, constant temperature of a cave and being able to control the light / achieve even lighting throughout the day assuming and electricity supply, without the intrusion of glare I have to contend with at home during the spring and summer appeals.
