Roman London - the London wall

These pages are based on a "Royal Commission On Historical Monuments 1834" - actually it is 1928; which is in the public domain.

(41). Upper Thames Street (A). Roach Smith records that in 1841 sewer excavations began at Blackfriars, but until the foot of Lambeth Hill was reached nothing was encountered ; they “ were there checked by a wall of extraordinary strength, which formed an angle with the hill and Thames Street ; upon this wall the contractor was obliged to open his course to a depth of about 20 feet so that the greater portion of the structure had to be over-thrown. ... It extends, as far as I had the means of observing, from Lambeth Hill to Queenhithe, with occasional breaks ; in thickness it measured from 8 to 10 feet ; the heights from the bottom of sewer was about 8 feet, in some places more or less; it reached to about 9 feet from the present street, and 3 feet from that which indicates the period of the Fire of London. . , . The foundation was made in the following manner :
oaken piles were first used ; upon these was laid a stratum of chalk and stones and then a course of hewn sandstones, from 3 to 4 feet by 2 and 2 1/2 feet, firmly cemented with the well-known compound of quicklime, sand and pounded tile. Upon this solid substructure was built the wall composed of rag and flint with layers of red and yellowy plain and curve-edged tiles. . . . Many of the large stones, above mentioned, are sculptured and ornamented with mouldings, which denote their prior use in a frieze or entablature of an edifice, the magnitude of which may be conceived from the fact of the stones weighing in many instances, upwards of half a ton. . .  I observed also fragments of sculptured marble had been worked into the wall, and also a stone carved with an elegant ornament of the trellis-work pattern, the compartments being filled alternately with leaves and fruit.
The fragments of marble pilasters and the fragment with trellis-pattern are now in the British Museum.

A piece of this wall was re-opened in October, 1924, in the construction of a sewer under Brooks Yard, from Upper Thames street, when the South wall of the city was tunnelled through. The foundation was laid between two rows of contiguous piles the tops of which were 14 feet below the roadway in Thames street; the total depth of the tunnel being 16 feet. The wall is of a concrete of Kentish rag-stone with a course of bricks a few inches below the tops of the piles. A second course of bricks was found 2 feet above that just described. Fifteen feet to the North of the main wall, and parallel to it was a second wall 5 feet thick, and with the foundation also between two rows of piles, but set apart. A thick bonding-course occurred just above the heads of the piles, and above this the wall was battered or coped back on both sides and finished with a flat top 2 feet wide. On the South face of this wall was a mass of puddled clay [Q W and Times, June 18th, 1925].
