The Whitechapel Fatberg Has Its Own Hidden Memorial

Back in 2017, an unusually large fatberg was discovered in the sewers beneath London, specifically in the Whitechapel area. The battle to break up and remove the fatberg was such a distinctive chapter in London sewer history that Thames Water has memorialized it with a manhole cover! While it looks like any other sewer entrance from a distance, the metal is embossed with "The Whitechapel Fatberg was defeated here in 2017."
