(23) . London Wall, between Throgmorton Avenue and Moor gate Street. The greater
part of this long stretch of wall was standing until 1817, when it formed the
back-enclosure of Bethlehem Hospital.
The destruction of 75 yards of it is recorded at that date, but without details as to its construction , The road was then widened towards the North, and now covers the site of the wall. A view of this section, dated 1812, is engraved in J. T. Smith, Ancient Topography of London, 28. In 1905 telephone-mains were laid, in the core of the wall, from Moorgate Street for a considerable distance eastwards. A manhole, sunk opposite No. 57, was carried down 15 1/4 feet through the wall, the base of which would appear to have been one foot lower.
