n gates. Its course can be traced
on any good map of modern Paris, and the size of the mediaeval city thus
compared with that of the present one. On the right bank of the river it
began with a tower that was called "the tower which makes the corner,"
and which stood near the northern end of the present Pont des
Saints-Peres. Thence it passed to the Porte-Saint-Honore, near the
present Oratoire and the statue of Coligny on the Rue de Rivoli, which
was defended by two towers, struck northerly to the site of the present
square formed by the intersection of the Rues Jean-Jacques-Rousseau and
Coquilliere, just north of the Bourse, where was a gate called Bahaigne.
Here it turned eastward, cut off the commencements of the Rues
Montmartre and Montorgueil, traversed also the Rue Francaise, and,
following the direction of the little Rue Mauconseil, arrived at the Rue
Saint-Denis, where was another gate called Porte-Saint-Denis, or Porte
aux Peintres. Continuing in this direction, it traversed the Boulevard
Sebastopol and the Rue Saint-Martin, enclosing the Rue aux Ours,
followed the Rues Grenier-Saint-Lazare and Michel-le-Comte, traversed
the Rue du Temple, and came to a tower erected nearly on the site of the
Mont-de-Piete of to-day, between the Rues des Francs-Bourgeois and des
Blancs-Manteaux, opposite to the Palais des Archives. Remains of this
tower were discovered in 1878, in demolishing some old houses to make
way for the enlargement of the Mont-de-Piete; it served to enclose a
circular staircase. The wall continued to follow the Rue
Francs-Bourgeois to another gate, the Porte Barbette, at the
intersection of the Rue Vieille-du-Temple with the Rue des Rosiers;
then, beginning to trend south, it followed nearly the Rue Malher to the
Place Birague, not far from where the Rue de Rivoli becomes the Rue
Saint-Antoine. Here was another gate, the Porte Baudet or Baudoyer.
Thence the line of fortification, crossing the locality of the present
church Saint-Paul-Saint-Louis, descended to the river in the direction
of the Rue des Barres, and ended on the quai, at the Porte
Barbel-sur-l'Yeau. Vestiges of this tower were also found in 1878.

On the south side of the river the wall was not commenced till 1208,
when that on the northern side was completely terminated. Instead of
making a close junction with that on the other shore, it took its start
somewhat to the eastward of the "corner tower," at the famous Tour de
Nesle, on the loca
