Ludwig Strasse and go down the Waisen Strasse, which brings you to the Brewery. Keep on down the same street with first the Brewery and then the Unschlitthaus on the right till you reach the river. Beyond the White Tower the moat was long ago filled up, but the section of it opposite the Unschlittplatz remained open for a longer period than the rest, and was called the Klettengraben, because of the burdocks which took root there. Hereabouts, on a part of the moat, the Waizenbräuhaus was built in 1671, which is now the famous Freiherrlich von Tuchersche Brewery. Here, too, the Unschlitthaus was built at the end of the fifteenth century as a granary. It has since been turned into a school. We have now reached one of the most charming and picturesque bits of Nuremberg. Once more we have to cross the Pegnitz, whose banks are overhung by quaint old houses. Their projecting roofs and high gables, their varied chimneys and overhanging balconies from which trail rich masses of creepers, make an entrancing foreground to the towers and the arches of the Henkersteg. The wall was carried on arches over the southern arm of the Pegnitz to the point of the Saumarkt (or Trödelmarkt) island which here divides the river, and thence in like manner over the northern arm. The latter portion of it alone survives and comprises a large tower on the north bank called the Wasserthurm, which was intended to break the force of the stream; a bridge supported by two arches over the stream, which was the Henkersteg, the habitation of the hangman or _Löb_ as he was called, of whom and of whose duties we shall have to speak in the next chapter; and on the island itself a smaller tower, which formed the point of support for the original, southern pair of arches, which joined the Unschlitthaus, but were so badly damaged in 1595 by a high flood that they were demolished and replaced by a wooden, and later by an iron bridge. After the great Wasserthurm, all trace of the old wall is lost. Probably it stretched in a straight line across the Weintraubengässlein, along the back of the houses of the Karlstrasse, and across the Irrergasse to the Lammsgasse. Mummenhoff fancies that he can recognise one of the towers of it in an exceptionally high house on the north side of this latter street. There too stood the _inner_ Neuthor. The houses at the back of Albrecht-Dürerstrasse show pretty clearly the further course of the wall until at the Thiergärtnerthurm it finally joined the fortifications of the Castle.
