Will Noble Leadenhall Market Is Wrapped In Giant Purple Tentacles Again

Leadenhall Market giant tentacles: Purple octopus like tentacles wriggle around the historic market — Leadenhall Market is one of the few buildings in London with its own Halloween costume.

If you walk by Leadenhall Market this October, you'll hardly be able to help but notice the six-metre-long purple tentacles wriggling out of the windows.

Not many London buildings have their own Halloween costume, but the City of London's Victorian market (aka Diagon Alley if you're into a certain wizarding saga) certainly does. Leadenhall Market first donned its monstrous calamari suit in October 2021, and must've received compliments, because it's worn the same outfit every year since.

Indeed, in 2024, the tentacles were even given a name: Professor Cephalus.

You can go and get snaps of the Professor between now and Halloween itself.

A small programme of Halloween events accompanies the Leadenhall tentacles, including:

🐙 Autumnal tea blending & ghost stories (27 October)
🐙 Halloween zine-making (28 October)
🐙 Halloween drag life drawing (29 October)
🐙 Halloween stitching bookmark workshop (30 October)
