As Halloween approaches each year, one of London’s most iconic landmarks, Leadenhall Market, dons its own “costume”—and this year is no exception. The market, renowned for its enchanting Victorian architecture, has once again transformed into a sea monster, with six-meter-long giant purple octopus tentacles spilling out from its windows.
“Professor Cephalus” Returns
First unveiled in 2021 with this colossal costume, Leadenhall Market drew such immense attention that the tradition has continued annually. In 2024, the giant creature finally received a name: Professor Cephalus.
This year, the Professor slithers through the market’s historic windows, creating a perfect Halloween photo opportunity for both locals and tourists.
