Before Henri IV, Paris had one stone bridge, the Bridge Notre-Dame; the wood bridges were often carried by the floods and the routs.

The Pont-Neuf had been started with Henri III, but the civil war had suspended work.

Henri IV made them begin again, and the Pont-Neuf, thrown between two very populated districts, became the point more attended of Paris.

Henri IV made at the same time build the houses of the Dauphine place, in the place of the waste grounds which finished the island Notre-Dame.

Finally a pump was used to feed from water the Louvre and Tileries: it was called Samaritaine of the name of a group out of bronze which decorated the frontage of the building.

Henri IV had left the Louvre in one fits with body discovered to go to the Arsenal, where he wanted to see sick Sully, when, to the entry of the street of the Ironwork, in a tightened place, at one time when the horses went to the step, a fanatic poor wretch, Ravaillac, were thrown on the king and twice inserted its dagger in the chest to him.

Henri subsided without pushing a cry, and its body was brought back to the Louvre: the best of the kings had died and its great projects with him; France was going to fall down in the disorder (May 14, 1610).

Ravaillac was condemned to an appalling torment: after having undergone torture with the Caretaker's lodge, it was led to the place of Strike and subjected during two great hours to new torments: one made him with clippers of large wounds where molten lead and ebullient oil were poured, then one burned the fist with the fire to him of suffers, finally one pulled about it with four horses.

An immense crowd charged it of imprécations, and as soon as he had died, the people rua on his body and tore it in thousand parts (May 27, 1610).
