Subterranean rivers of London
The subterranean or underground rivers of London are or were the direct or indirect tributaries of the upper estuary of the Thames that were built over during the growth of the metropolis of London. They now flow through culverts, with some of them integral parts of London's sewerage system and diverted accordingly.
