then followed the line of the latter street, crossing the Boulevard St. Germain, and continued by the Rue de l'Ancienne Comédie. In the Cour de Rouen, No. 61 Rue St. André des Arts, an important remnant may be seen with the base of a tower. We may now trace the march of the wall and towers by the Rues Mazarin and Guénégaud, where at No. 29 other fragments exist, to the south-west water-tower, the notorious Tour de Nesle[50] whose site is occupied by the Hôtel des Monnaies. The passage of the Seine was blocked by chains, which were drawn at night from tower to tower and fixed on boats and piles. The wall was twenty years building and was completed in 1211. It was eight feet thick, pierced by twenty-four gates and fortified by about five hundred towers. Much of the land it enclosed was not built upon; the _marais_ (marshes) on the north bank were drained and cultivated and became market and fruit gardens. The moated château of the Louvre, another of Philip's great buildings, stood outside the wall and commanded the valley route to Paris. It was at once a fortress, a palace and a prison. Parts of two wings of the structure are incorporated in the present palace of the Louvre, and the site of the remaining wings, the massive keep and the towers are marked out on the pavement of the quadrangle. Many are the stories of the great king's wisdom. One day, entering the chapter-house of Notre Dame during the election of a bishop, Philip seized a crozier and passing along the assembled canons thrust it into the hands of one of lean and poor aspect, saying: "Here, take this, that you may wax fat like your brethren." His jester once claimed to be of his family through their common father Adam, and complained that the heritage had been badly divided. "Well," said the king, "come to me to-morrow and I will restore what is due to thee." Next day, in the presence of his court, he handed the jester a farthing, saying: "Here is thy just portion. When I shall have shared my wealth with each of thy brothers, barely a farthing will remain to me."
