Prisoners died of its stench, and of the diseases which it carried with it. In the valley of the Fleet, wrote a doctor in 1560, and “in its stinking lanes, there died most in London and were soonest inflicted, and were longest continued, as twice since I have known London I have marked it to be true.” In later testimony quoted in
Every attempt to render it clean or noble failed. After the Great Fire, when the wharves along the Thames were utterly destroyed with all their merchandise within them, its banks were raised upon brick and stone while four new bridges were constructed to maintain its formal harmony. But the refurbishment of the New Canal, as it was then called, was not successful; the waters once more became sluggish and noxious, while the neighbouring streets and banks continued their notorious lives as harbours for thieves, pimps and malingerers. So, within fifty years of the grand development, the river itself was bricked over. It is almost as if it represented a flow of guilt which had to be concealed from public view; the city literally buried it. In 1732 it was bricked in from Fleet Street to Holborn Bridge and then, thirty-three years later, it was bricked in from Fleet Street to the Thames. At the beginning of the next century its northern reaches were buried underground so that no trace of this once great guardian of London remained.
Yet its spirit did not die. In 1846 it blew up, “its rancid and foetid gas,” trapped within brick tunnels, “bursting out into the streets above”; three posthouses were swept away by “a tidal wave of sewage” and a steamboat was crushed against Blackfriars Bridge. The waters of the Fleet Ditch then actively hampered the efforts to construct an underground railway beneath it: its waters filled the tunnels with dark and fetid liquid, and for a while all work was abandoned. It is now employed only as a storm sewer, with its outfall into the Thames by Blackfriars Bridge, but it still manifests its presence. In storms it may still flood the roadway, while building works upon its old course have regularly to be pumped out. So the waters from ancient streams and wells collect themselves in their old courses and run along the familiar beds of the now enclosed main rivers.
The rivers themselves are not wholly dead, then, and occasionally emerge into the light. The course of the Westbourne River can be observed rushing through a great iron pipe above the platform of Sloane Square Underground Station; the Tyburn is also carried in great pipes at the tube stations of Baker Street and Victoria. In February 1941 the Tyburn was observed flowing at the bottom of a bomb crater. The Westbourne was not covered until 1856.
