Panoramic view on the rooftop of CNIT (Centre of New Industries and Technologies).

CNIT was built in 1958. Its architects are Robert Camelot, Jean de Mailly, Bernard Zehrfuss and Jean Prouvé. In 2010, the building still has the largest range of concrete arch in the world: 218m.

Michael Holley is the architect who designed the district Olympiads in the 70s. This district stretches from the Place d'Italie to the boulevards of the Marshals. The tower Antony and Cleopatra is unusual because it is the only one with an original form. All other towers in the area are rectangular.

The height of the tower is 104 meters. It has 37 floors (official). It largely dominates the surrounding towers.

Quarries of Saint-Cloud, in the Trocadero Park

The underground quarries of Saint-Cloud (of coarse limestone) are used as building stone. The grand facade of the Colonnade of the Louvre is partly made with this stone. The rest comes from the underground quarry of Saint-Leu Esserent. It also used the stone to build the castle of Saint-Cloud, located a few tens of meters from the quarry.

The walls of building quarry were partially dismantled to get new stones. They were used to renovate the castle of Saint-Cloud in the 19th century. However, the consequences of a large fire, the foundations were razed. The stones stolen are become useless.

The quarry of Annet on Marne is called "Purpled". The all quarry is in bad shape. Ceils are down on many places. See this pillar who does not support the ceil anymore...

The structural wood burned in a fire in 1836. the wood structure was replaced by a metal frame. There was restoration work in 1995 because she was aging. Photographs were taken by a photographer Regional. His photographs are exhibited in a room halfway up the blazing gotical tower.

The construction of the castle Regnéville-sur-Mer dates from the ninth century. The castle was the witness of many battles between French and English during the Hundred Years War. In the 17th century, the fortress was destroyed by order of Cardinal Richelieu. One wall of the castle flew to the bottom of the church. Today, there are only very little of the original castle (there is a tower collapsed at half) but this crypt is still beautifully preserved.

The creation of a railway track near Paris was decided in 1851. Very quickly, the main stations of Paris are linked, including that of Bercy. In 1867, the loop is completed.

Following the increase in passenger traffic on the subway, going to the inner ring decreases. In 1934, there is more train traveler. Only freight trains. In 1993, the entire line is abandoned, with the exception of the line that runs along the banks of the Seine, used by commuter trains.

This cathedral was hurt by the storm of january 2009. Some peaks are missing.

The underground limestone quarry of Bazemont, located in the Yvelines, was exploited for its rough limestone. There are still several excavations along the quarry road. People said in the village that the steeple of the cathedral of Chartres was built with stone from this quarry.

The quarry is also witnessed the wars of the 19th century. There are many drawings of ancient time. Drawings of soldiers, praise God, graffiti. Second quarries are reused in mushroom places. You can see the remains of the culture of the mushroom into stacks.

People of Bazemont also operated quarries in manufacturing lime from limestone. A furnace that access was by way of Grignens are still at the bottom of the valley Rogère.

Quarries of Herblay are over 14km wide and some hundreds of meters deep, on hillsides along the Seine.

In 1776, the exploitation of new underground quarries in Paris was forbidden. People had to take the stone elsewhere. It is for this reason that the quarry was known as "Imperial quarry" or "Quarry of the city of Paris". They built many monuments in Paris with this stone because it was high quality (the famous Royal stone).

Among the monuments built, there was The Pantheon of Paris, Department of Marine Place de la Concorde, the Gare de l'Est, the mint as well as many statues at Versailles.

The network's quarries has been excessively exploited in Herblay. The ceiling is fragile and the walls separating the tunnels are very thin. To reinforce the quarry, they have added many pillars and reinforcement structures.

Later, like many underground quarries, they served to mushroom plantation in the 1980s. The workers have dug additional corridors between small quarries networks.

A few years later and they were gradually abandoned. The latest mushroom plantation closed in 1995.

Since 2003, the association "Herblay heritage" has undertaken to make public visits to the part of the "English entry" with the famous double-arched vault and pretty ponds.
