Between Great Tower Hill and Little Tower Hill (Strype, ed. 1720-O.S.25, in 1880).
Seems to have been formed early in the 18th cent., between 1708-20, and was in some parts only 25 ft. wide (See Lond. St. Impts. 1855-97, p.91).
Removed 1882-7 for formation of a new street from Mark Lane to Tower Hill in consequence of extension of the Metropolitan Railway and the consequent widening of Eastcheap and Gt. Tower Street (See ib.).
Named after the Tower Postern.
A portion of the old Wall was discovered here in 1852, reaching to a height of 25 ft., now hidden by buildings. A length of 73 ft. was removed in 1882 for the Metropolitan Railway, and foundations of a building and a red tesselated pavement were unearthed.
