Paris remained for many centuries in its island state,with two bridges,one on the north,the other on the south;and two bridge heads,which were at the same time its gates and its fortresses,--the Grand-Chatelet on the right bank,the Petit- on the left.

• 以后若干世纪，巴黎依然是岛屿状态，有两道桥，一南一北，有两个桥头堡，既是城门又是堡垒，右岸的称大堡，左岸的叫小堡。
