The Pont au Change and its Sounds

MORE RESEARCH FOR my Paris Bridges project took me to a bridge right in the heart of Paris the other day, the Pont au Change.


The Pont au Change connects the Île de la Cité, one of the two natural islands in the Seine (the other being the Île Saint-Louis), to the Right Bank.

When Julius Caesar arrived in 52 BC, the island we now know as the Île de la Cité was a Gallic settlement, home to the Parisii tribe. A low-lying area subject to flooding, the island was quite an inhospitable place but it did offer a convenient place to cross the Seine and a refuge in times of invasion. Although they set up camp there, the Romans didn’t like the island much and they began to develop their more permanent settlement, Lutetia, in the healthier air on the slopes above the Left Bank of the river.

It is thought that a wooden bridge crossing La Seine at or somewhere near today’s Pont au Change existed before the Romans arrived. A stone bridge was built in the 9th century at around the time of the Viking invasion and there have been several others since.  Known until the late 13th century as the Grand Pont, this bridge was a major medieval artery connecting the Île de la Cité to the developing Right bank of the Seine. The Grand Pont may have been important but it was very inefficient. Like the narrow, winding streets surrounding it the bridge was perennially over-crowded making it difficult to transport goods through the city – not to mention the high risk of accidents from the traffic. In 1131 Louis VI’s son and heir was killed when a runaway pig caused him to be thrown from his horse.

By the end of the 13th century a large number of Italian money-changers, mainly natives of Lombardy, had established themselves in Paris. At the time when the King and the lords of his court sold prebendaries, bishoprics and benefices by auction the Lombards lent money at a high rate of interest and made immense fortunes. In 1296 a new Grand Pont was built and by Royal decree these money-changers were obliged to conduct their business out in the open on this new bridge and so it became known as the Pont aux Changeurs or Pont au Change (Exchange Bridge).

In 1621 this bridge was completely destroyed by fire. The money-changers asked the King for permission to rebuild the bridge at their own expense, provided that they could erect houses on it and this was approved by Royal edict in May 1639. The new bridge, built between 1639 and 1647, comprised seven stone arches and at 32 metres wide it became the widest bridge in the city at the time.

In the mid-19th century the Pont au Change came under the scrutiny of Baron Haussmann and his urban redevelopment of Paris. To fit with Haussmann’s plans, the bridge needed to be realigned and so in 1858 work began on a new bridge.

Designed by the French engineers, Paul-Martin Gallocher de Lagalisserie and Paul Vaudrey, the new Pont au Change was opened on 15th August 1860 and it’s the bridge we see today.


The bridge comprises three elliptical arches, each with a 31 metres span, it’s 103 metres long and 30 metres wide with an 18 metre roadway and two pavements each 6 metres wide.

The Pont au Change connects the Île de la Cité from the Palais de Justice and the Conciergerie on the Left Bank to the Place du Châtelet on the Right Bank. The Voie Georges Pompidou, a two-lane road, runs under the arch closest to the Right Bank. For most of the year this road carries a seemingly endless stream of traffic but for part of July and August each year traffic is forbidden, tons of sand are brought in and this road becomes part of the popular Paris-Plages, the seaside in Paris.

My Paris Bridges project is not only about tracing the history of all the thirty-seven bridges that cross La Seine within the Paris city limits, it’s also about trying to identify and to capture the characteristic sounds of each bridge.  And identifying and then capturing these characteristic sounds is not as easy as it might seem, it involves a lot of time, legwork and endless patience.

All the bridges included in my Paris Bridges project have two things in common, they all cross La Seine and they are all within the Paris city limits. You might therefore conclude that their characteristic sounds are also likely to have things in common – the sound of water, the sound of river traffic and the sound of endless vehicular traffic.  And of course, this is true – at least up to a point. But it doesn’t necessarily follow that the sounds of the water and the river and vehicular traffic will be the same at each bridge – at least not if you’re an acute listener. And what about the other sounds, are there any sounds that are unique to any particular bridge?

Previously, I’ve published posts about the Pont National and the Pont de Bercy both of which have unique sounds, trams running over the former and the Métro running over the viaduct on the latter – and the Pont au Change too has its own unique sound.

But before we come to that unique sound, it can’t be denied that both the water and the traffic are integral parts of the sound tapestry of the Pont au Change.

I went down to the Voie Georges Pompidou to explore the sounds under the bridge. I stood under the arch close to the road facing into the bridge with the traffic passing me from right to left.

Pont au Change – Under the bridge:

Listening to sound is a very subjective thing. Whether or not you find these sounds of the traffic passing under the bridge interesting or maybe even enjoyable is a matter of personal taste, but in my opinion at least, these sounds have a value. They may be just the sounds of passing traffic but they are a documentary record of the sounds in this place on a particular day in 2014 and they are some of the characteristic sounds associated with the Pont au Change. Personally, I find that these sounds have a rhythm to them that becomes absorbing with repeated listening.

Interestingly, the traffic passing along this road sounds completely different when listened to from the Quai de Gesvres above.

And what about the other characteristic sounds we might expect to find at a Paris bridge – the sounds of water perhaps?


Pont au Change from the Quai de la Corse 

Recording the sounds of the water from the Voie Georges Pompidou would have been a thankless task not only because it would be perilous in the extreme but also because the sound of the passing traffic is all consuming. There seemed to be better prospects though on the opposite side of the river.

From the Quai de la Course a set of stone steps leads down to and then below the water. Looking at the Pont au Change from here on this very dull and overcast day reminded me that in Victor Hugo’s novel, Les Miserables, police Inspector Javert finds himself unable to reconcile his duty to surrender Jean Valjean to the authorities with the fact that Valjean saved his life. Javert comes to the Pont au Change and throws himself into the Seine.


With no wish to throw myself into the Seine I ventured down the steps and began to record.

Pont au Change – Water at Quai de la Corse:

Echoes of Inspector Javert though were present in the shape of the police sirens in the distance and then the sound of a rubber dinghy containing three police frogmen armed to the teeth zooming by. It seems that I had chosen to visit the Pont au Change on the same day that the President of China had chosen to visit Paris so presumably the frogmen were part of the elaborate security apparatus.

While the sound of the passing dinghy is not a characteristic sound of the Pont au Change, it just happened to be there at this time on this day, the sound of the water certainly is.

Perhaps it’s worth pausing to consider what I mean by ‘characteristic’ sounds.

Most of the sound work I do in Paris is concerned with the concept of ‘sound’ and ‘place’ – the relationship between the two and particularly how sound can help to define a place.

In the context of my ‘Paris Bridges’ project, I’m seeking to find the characteristic sounds that define each bridge. I’ve already said that the sound of water and of river and vehicular traffic are pretty much common to all the bridges within the Paris city limits but that doesn’t mean that these sounds are all the same. The sounds of the Bateaux Mouches passing under the Pont Saint-Michel are very different to the sounds of the same boat passing under the Pont des Arts for example. The sounds of the water at the foot of the steps at the Pont au Change are different from the sounds of the water at the Pont Neuf, the next downstream bridge, and the sounds of vehicular traffic passing under the Pont au Change are very different to the sounds of the traffic passing over it as we shall see in a moment.

I contend that the sounds of water and of river and vehicular traffic are ‘characteristic’ sounds of the Paris bridges and, if listened to carefully enough, the very subtle differences can help to define each bridge. My real challenge though is to find the characteristic sounds for each bridge that don’t require an explanation or expert listening, the sounds that simply shout out, “I’m here, I’m unique, I AM the sound of this bridge!” I’ve already mentioned two examples, the trams running over the Pont National and the Métro running over the viaduct on the Pont de Bercy but for some other Paris bridges such obvious defining sounds may be harder to find.

What makes these sounds ‘characteristic’ though, whether they are very subtle or very obvious, is that they are permanent. They are not simply passing sounds like the police frogmen that might be there one day and not the next; they are always there – at least until some major reconstruction takes place that removes them.


The Pont au Change and the Conciergerie

And so, back to the Pont au Change.

Between the pavements on either side of the Pont au Change is a roadway layered with pavé. Clearly, the sound texture of the traffic passing over this pavé surface on the bridge is going to be different from the sound of the traffic passing over the tarmac road under the bridge.

But as well as the rather subtle sounds of the traffic over the pavé, is there a more obvious sound at the Pont au Change, a sound that shouts out and demands to be heard?

In my Paris Soundscapes Archive I have some sounds of Paris that last for over an hour and some that last only for seconds. Often, the shorter sounds can say as much as the longer ones. In the midst of all the sounds on the Pont au Change there is a sound that really defines this bridge. When I was at the bridge this sound only lasted for about three-seconds (sometimes it’s shorter and sometimes it’s longer) but while the sounds of the passing traffic and the people are transient, this sound is permanent and it has been heard here for hundreds of years. It’s the sound of l’Horloge du palais de la Cité, the oldest public clock in Paris.


Pont au Change – l’Horloge du palais de la Cité

Pont au Change – On the bridge:

The clock is to be found in the Northeast corner of the Palais de Justice at the Left Bank end of the Pont au Change and its chimes can be heard across the bridge. It dates from 1370 and it was built and installed by at the behest of Jean le Bon (John the Good), King of France from 1350 until his death in 1364.

At this part of the Palais de Justice is la Conciergerie, both a former Royal Palace and later, a notorious prison. As chance would have it, I recorded the clock chiming at three o’clock in the afternoon. At exactly the same time on 17th July 1793 Charlotte Corday was sentenced inside the Conciergerie to be executed by guillotine for the assassination of the Jacobin leader Jean-Paul Marat during the French Revolution. While she was being sentenced this same clock would have been chiming outside as it would at eight o’clock the same evening when she was beheaded.

The clock has been restored several times throughout its lifetime, the latest restoration being in 2012, and today it looks and sounds probably better than it has ever done.

My exploration of the Pont au Change has taken me from the home of the ancient Parisii tribe on the swampland of an island in the middle of La Seine, to a Roman and then a Viking invasion, to the Lombardy money-changers, to Jean le Bon’s public clock, to the French Revolution and to Baron Haussmann’s urban development of Paris. And let’s not forget police Inspector Javert from Victor Hugo’s Les Miserables … and three armed police frogmen.

I’ve also tracked down and captured the contemporary sounds of the Pont au Change – the sounds that I believe are the characteristic sounds of this bridge.

And yet, one mystery remains.


Halfway down the steps leading to the river from the Quai de la Corse are the remains of a window and a shuttered doorway in the wall. Even though there are no houses anywhere on this side of the Quai de la Corse the number 21 appears above the door.

What is this place and what stories lie within?

I can’t help feeling that police Inspector Javert is keeping a beady eye on it from his watery grave.
