In September last year, a monster was discovered in London's sewers.
Weighing about 130 metric tons and measuring 250 meters in length — longer than the city's Tower Bridge — a congealed mass of fat, oil, wet tissues, condoms and diapers was found blocking a section of the wastewater network during a routine inspection.
The giant "fatberg," subsequently nicknamed the "Monster of Whitechapel," took a team of eight workers toiling nine hours a day, seven days a week, more than two months to break down. A chunk of the fatberg later went on display at the Museum of London.
