Why Is There Water Under the Paris Opera House?

By Alice Nichols

Have you ever heard of the Paris Opera House? It’s a grand building with a rich history, known for its stunning architecture and as the setting for Gaston Leroux’s novel, The Phantom of the Opera.

But did you know that there is something mysterious going on beneath this iconic landmark? Water. Yes, water.

What’s the story behind it?

Well, it all started in the 1800s when the Opera House was being built. The construction site was located right next to a lake called Lac de la Buzenière.

To create a strong foundation for the building, workers had to pump out water from the lake. Despite their efforts, they were unable to completely drain it and so some water remained under the foundation.

Over time, as Paris’ urbanization increased and its population grew, more buildings were constructed around the area and caused underground waterways to shift. This led to an increase in water pressure which caused groundwater to seep into the basement of the Opera House.

So how does this affect the Opera House?

The presence of water underneath has caused many problems for this iconic structure over time. One major issue is that it has damaged the foundation of the building which can lead to structural instability. To prevent this from happening, engineers have had to install pumps in order to continuously remove excess water from underneath.

Another issue is that it has led to mold growth within parts of the building due to high humidity levels. This can pose a risk not only to visitors but also performers who spend long hours rehearsing and performing on stage.

But why can’t they just fix it?

Unfortunately, fixing this issue is not as simple as just draining out all of the water from underneath. The reason being that if all of that weight were removed suddenly from under such an old structure, it could cause further damage or even collapse.

Instead, engineers have been working on a long-term solution to manage the water levels under the Opera House. This includes installing more advanced pumping systems, as well as creating underground drainage canals to divert water away from the building’s foundation.

Conclusion

In conclusion, the presence of water under the Paris Opera House is not just a curious aspect of its history but also a major issue that has caused damage and problems for this iconic structure over time. However, it’s reassuring to know that engineers are working on a long-term solution to manage and mitigate these issues.

As visitors and admirers of this beautiful building, it’s important to appreciate not only its grandeur but also its complexity and the challenges that come with maintaining such a historic landmark.
