Wall of Charles V

The wall of Philippe Auguste was created at the beginning of the 13th century and enclosed 253 hectares with houses and vegetable and vine fields allowing people to protect from a possible military siege. But decades later, the fields had been replaced by homes and crops had been pushed outside the city walls. Several suburbs were growing rapidly, particularly in the west. The growing population could no longer be contained in the city. Furthermore, with the Hundred Years War, it became necessary to build a new enclosure to protect the capital of France.

The bastion and the walls of la Bastille in the eighteenth century

Étienne Marcel, provost of the merchants, began to build a moat from 1356, a few hundred yards beyond the wall of Philippe Auguste. Only the right side was affected by this expansion. King Charles V, from 1358, ordered the fortification and the addition of a large and deep ditch that would be filled by the river Seine.

The new fortification extended westward beyond the Louvre, which lost its function as a fortress. Charles V transformed the Louvre into a residence, but without changing its dimensions. He established a library there with 973 books.

On the east, the new home of the King, the Hotel Saint-Pol, was poorly protected. Charles V decided to build the Chastel Saint-Antoine, the Parisians called it the Bastide Saint-Antoine, then la Bastille (Bastide or Bastille is an old French word for castle). In 1370, the provost Hugues Aubriot laid the cornerstone of the building which was completed in 1382. The city then spread over 440 hectares (1,100 acres) with more than 150,000 inhabitants.

The wall, as well as its extension built by Louis XIII on the west side was destroyed in 1670, on orders of Louis XIV after his victories in the Netherlands and Germany.
