The City sewers are the oldest in the capital, for the very plain reason that the City itself, in its site, if not now in its public and private buildings, is the oldest part of London, as regards the abode of a congregated body of people.
The ages (so to speak) of these sewers, vary, for the most part, according to the dates of the City’s rebuilding after the Great Fire, and according to the dates of the many alterations, improvements, removal or rebuilding of new streets, markets, &c., which have been effected since that period. Before the Great Fire of 1666, all drainage seems, with a few exceptions, to have been fortuitous, unconnected, and superficial.
The first public sewer built after this important epoch in the history of London was in Ludgate-street and hill. This was the laudable work of the Dean and Chapter of St. Paul’s, and was constructed at the instance, it is said, and after the plans, of Sir Christopher Wren. There is, perhaps, no official or documentary proof of this, for the proclamations from the King in council, the Acts of Parliament, and the resolutions of the Corporation of the City of London at that important period, are so vague and so contradictory, and were so frequently altered or abrogated, and so frequently disregarded, that it is more impossible than difficult to get at the truth. Of the fact which I have just mentioned, however, there need be no doubt; nor that the second public City sewer was in Fleet-street, commenced in 1668, the second year after the fire.
There are, nevertheless, older sewers than this, but the dates of their construction are not known; we have proof merely that they existed in old London, or as it was described by an anonymous writer (quoted, if I remember rightly, in Maitland’s “History of London”), London “ante ignem”—London before the fire. These sewers, or rather portions of sewers, are severally near Newgate, St. Bartholomew’s Hospital sewer, and that of the Irongate by the Tower.
The sewer, however, which may be pointed out as the most remarkable is that of Little Moorgate, London-wall. It is formed of red tiles; and from such being its materials, and from the circumstance of some Roman coins having been found near it, it is supposed by some to be of Roman construction, and of course coeval with that people’s possession of the country. This sewer has a flat bottom, upright sides, and a circular arch at its top; it is about 5 feet by 3 feet. The other older sewers present much about the same form; and an Act in the reign of Charles II. directs that sewers shall be so built, but that the bottom shall have a circular curve.
I am informed by a City gentleman—one taking an interest in such matters—that this sewer has troubled the repose of a few civic antiquaries, some thinking that it was a Roman sewer, while others scouted such a notion, arguing that the Romans were not in the habit of doing their work by halves; and that if they had sewered London, great and enduring remains would have been discovered, for their main sewer would have been a solid construction, and directed to the Thames, as was and is the Cloaca Maxima, in the Eternal City, to the Tiber. Others have said that the sewer in question was merely built of Roman materials, perhaps first discovered about the time, having originally formed a reservoir, tank, or even a bath, and were keenly appropriated by some economical or scheming builder or City official.
“That the Britons,” says Tacitus in his “Life of Agricola,” “who led a roaming life, and were easily incited to war, might contract a love for peace, by being accustomed to a pleasanter mode of life, Agricola assisted them to build houses, temples, and market-places. By praising the diligent and upbraiding the idle, he excited such emulation among the Britons, that, after they had erected all those necessary buildings in their towns, they built others for pleasure and ornament, as porticoes, galleries, baths, and banqueting-houses.”
The sewers of the city of London are, then, a comparatively modern work. Indeed, three-fourths of them may be called modern. The earlier sewers were—as I have described under the general head—ditches, which in time were arched over, but only gradually and partially, as suited the convenience or the profit of the owners of property alongside those open channels, some of which thus presented the appearance of a series of small uncouth-looking bridges. When these bridges had to be connected so as to form the summit of a continuous sewer, they presented every variety of arch, both at their outer and under sides; those too near the surface had to be lowered. Some of these sewers, however, were in the first instances connected, despite difference of size and irregularity of form. The result may be judged from the account I have given of the strange construction of some of the Westminster sewers, under the head of “subterranean survey.”
How modern the City sewers are may best be estimated from the following table of what may be called the dates of their construction. The periods are given decennially as to the progress of the formation of new sewers:—
