Open &Closed public space at the Square du VertGalantMain public spaces along the West-East axis

1. Forewords
a. The aim of the International Workshop is to allow Japanese,
Chinese and French students to exchange opinions and compare theircultural perceptions of public spaces while working together on anarchitectural project.
For this project, student groups should bring answers to questions
such as:What is a public space?
Why are these spaces so important?
Which concepts would better respond to it?
What kind of social interactions should occur?
Through visits of the banks of the Seine, the “Square du Vert-Galant”
and the “Ile de la Cité”, students should produce an analysis of thecontext to propose an architectural project capable to give a relevant
vision of the “Vert-Galant square” that would project it into the future,
without hindering its current qualities.

The West-East axis, from Saint-Antoine gate
(Bastille) to Saint-Honoré gate, aligns the main
public spaces of Paris

The Saint-Antoine Street, large and popular
public spaceb. Paris has a long history of public spaces because its citizens areused to express some of their highest social values in these spaces.
The first public space, and maybe the most important of all, is thestreet. That’s where the difference between public and private
expresses itself immediately. The history of France is linked to someparisian streets. We often hear the phrase: «citizens will take thestreets!» when something does not run socially well.
But some public spaces are more «social» than others. While moststreets are public but restrained to a neighbourhood, some converge
to crossroads to form larger spaces; others will bring people toimportant public buildings, such as the ancient “Place de Grève”,
current place de l”Hotel de Ville, where Paris City Hall is located. Since
the Middle Ages it is where citizens gathered for announcements,
jousting, public ceremonies or public executions. This kind of space
allows social expression and will to become powerful and politicaly
audible.
These larger public spaces which interest us have some common
characteristics: they are open, easily accessible and frequently usedby citizens in everyday life. They are large enough to allow for publicgatherings, they have particular architectural styles, and they open theview through cut outs and perspectives that link important points of the

city.

2. The site of the project: The “Square du Vert-Galant”,
75001 Paris.
The square is situated in the west end of the “Ile de la Cité” as the bowof a gigantic vessel coming down the Seine river with the Notre Damecathedral as its main load.
The vessel seems to be attached to firm land by the “Pont-Neuf”

bridge through its two sections that span the Seine. The “Ile de laCité”, the City Island, is where you’ll find the oldest foundations ofParis.
That’s where the Romans have built the Jupiter’s temple and thegovernor’s palace. Later on, the Merovingians kings of France built
the first royal palace. It became later the Parliament of Paris and it istoday the Justice Palace. Parts of the ancient palace are still visible, as
the “Conciergerie” towers. You’ll find here Gothic monuments such as
the “Sainte-Chapelle” and “Cathédrale Notre-Dame”. Just behind the“Square du Vert-Galant”, you’ll find the triangle of the “Place Dauphine”
and the equestrian sculpture of king Henry IV.
The end of the “Ile de la Cité” has been the place of many projects
since its origin. It may look as «logical» and natural today when seenfrom the “Pont des Arts”. But it is the result of an accumulation of
successive designs through the centuries. It was a small royal garden
in the Middle Ages. It was replaced by the “Place Dauphine” with a
Renaissance style; but the main change came with the construction of
the first stone bridge of Paris, the “Pont-Neuf” (which is also the oldest
bridge in Paris) with its impressive dimensions, 238 m long and 20 m
wide. A sculpture of Henry IV was built to crown this end of the island(several sculptures since 1664). The actual sculpture with its hugepedestal echoes the “Pont Neuf” design since 1818.

Citizens admiring the Pont-Neuf, first stonebridge, the oldest one of Paris

Until 1884 and the construction of the square of “Vert-Galant” with its
pure triangular form, the west end had the image of the statue facing
towards “Place Dauphine”, turning its back to the river and the Louvre.
On this small area of land, 7 meters below the statue, people came tobathe and swim in the river. A cabaret that existed in this place wasdestroyed by the flood of 1879.
When you’ll walk on the “Pont des Arts”, the view that you’ll see of the“Ile de la Cité” today, is the successful result of a series of designs thatgave to the island its current shape. The project that you’ll conceive,
will bring another layer to this accumulation of influences.
All around of the “Square du Vert-Galant”, you’ll find some of the mostimportant monuments of Paris. On the right bank: The Louvre, theCity Hall, the gothic church of “Saint Germain l’Auxerrois”, among
others. On the left bank, “le Palais de la Monnaie” and the “Institut de

France”.

3. The Seine river
From both sides of the island, there is the Seine. The larger side
measures 106 m, and the smaller 20m . Paris became the mostimportant city of France, its economic and political heart thanks to the
Seine river. If the island isthe heart of Paris, the Seine should be thevein that brings blood and the strength that makes the heartbeat.
From the square, one can see the impressive number of bridges
that cross the Seine and link the two banks of Paris. Upstream; the“Pont au Change”, the Notre Dame bridge, the Saint-Michel bridge,
the “Arcole”, and the “Pont de l’Évêché”. Downstream ; the “Pontdes Arts”, the Carrousel bridge, the Royal bridge, the “Pont de laConcorde”, the Alexandre III bridge. Also, from this location, you can

where the “l’Arc de Triomphe” is located).

4. Context and atmosphere in the “Square du VertGalant”
The square, built just below the “Pont-Neuf” was conceived as a visualextension of the pedestal bloc of Henry IV’s statue reconstructed in the
beginning of XIX century.
The square was formed by merging three small islands that previously
existed to produce it’s characteristic triangular shape. Was it inspiredby the triangular form of the “Place Dauphine”? Do they both justfollow the natural form of the island? The form brings a dynamic end
to the “Ile de la Cité” as a vessel. This first and immediate impressionof the square has great importance to any project to be built in thisplace.
But also, the square has preserved its ancient purpose of leisure in
the sand banks of the river. It is in fact a very calm and small garden
composed of a grass area, a hedgerow and some trees. People
come here for its calm atmosphere, to cool down under the shade of
the trees. The garden is surrounded by a stone walkway that allows
to walk around it and to sit down close to the water. The view of theSeine under the shadows of the weeping willow trees, at the veryedge is quite mesmerising. It gives the impression of a timeless place,aside from the urbis. In fact, when in the “Vert-Galant”, one feels
disconnected from Paris. The reverse is true, Parisians see it as an
outside spot as it does not follow the same rhythm of the city.

On its north bank there are the boats «Vedettes du Pont -Neuf» thathave been installed since the beginning of the 60’s. Should they be
moved to the other opposite bank that has been recently redesigned
for pedestrians?

5. The outgoing program:
The program will be proposed as a result of the analysis and intentionsof each group.

A wonderful place to fish and chill

Considering the uniqueness of its situation in Paris, it’s historicalas well as geographical context, an artistic and creative approach is
required.
The project should respond to a dual issue:

5.1. An Open space should be conceived as an architectural

installation with a strong aesthetical aim. The usage of this space is tobe proposed by each group.
Should it be useful or not, each group will adapt it to the project
aims. The romantic character of the site should be considered. The
proposition should not have a commercial purpose and will suggest aplace for contemplation, dreams, pause, rest, and the desire to be incontact with beauty.
The interaction between art and nature is a major consideration for
all propositions. What we understand here by art: artefacts, as things

The project will be considered as temporary and to be replaced withina period to be determined. For this first proposition, the project will bean echo for the Olympic Games that Paris will hold in 2024. (Surfaceof the actual garden: 1300 m2)
Reference 1: The Pont-Neuf wrapped, 1985, installation by Christo
and Jeanne-Claude.
Reference 2: the Serpentine in London, where architects have beenbuilding great concepts that expresse their views of space, art, living...
etc.

Nouvel (references)

Reference 3: the “Festival international des jardins of the Domaine deChaumont-sur-Loire”, annual completion for creative gardens of theChaumont Domaine.

5.2. A Closed space should be conceived as a floating barge

to be on the Seine. This space will be considered as an extensionof the open part of the project. The artistic orientations of the Openspace, will be extended in the Closed space, conceived for exhibitions,conferences and other uses in connection with the group choices. A
coffee place would be necessary.

Surface of the barge: 300 m2 each level; one level over le water level
maximum.
Location of the barge : On the larger side of the Seine. A few meters
after the “Vedettes”, if they should remain at their actual location.
Or, in their place. In this case, the “Vedettes” would be moved to the
Right bank. (Surface of the square : 2850 m2 Surface of the garden :1300m2)

Pedestrian access : by existing stairs of the “place du Pont-Neuf”. A
lift for handicaped people should be designed. River access : to beconsidered.

Square du Vert-Galant
75001 Paris
When we arrived on the site, we entered in the square throughtwo dark stairs going down. We thought that this circulation
wasn't very welcoming so we decided to work on this issue.
Our main idea was to create a walk, starting on the mainplace and going down to the garden.
We created a « floating » structure made in wood with platform used as circulations spaces, while the others platforms
create spaces where people could meet, chill, read, etc. We
thought the access and the barge like an unique entity. They
are connected to one another. This way of entering the site,playing on levels gives peoples several views and place toenjoy the landscape.
This system of platform continues on the Island, floatingover the water, among the tree to finally finish softly thetriangular shape of the island in the water.
