itison have announced the return of the UK’s biggest Halloween event, GlasGLOW, to the Botanic Gardens in Glasgow with a brand new show, following three sell-out years.
The show will create over 150 jobs and generate a multi-million-pound windfall for the local area. GlasGLOW takes place as the biggest climate change summit, COP 26, comes to Glasgow with show creator Oli Norman writing a story based on the global climate crisis.
Guests will enter the fictional world of Glasglopolis, a sprawling metropolis which is under attack from a terrifying toxic gloop. Playing the role of an undercover reporter, each guest will go on a journey to expose the truth and save the city’s annual pumpkin festival.
Set to run from the 27th October to the 7th November, GlasGLOW will once again transform Glasgow’s Botanic Gardens into an immersive journey created by a world class team of sound, lighting and set designers. Event goers will become part of the story as they work to uncover a toxic threat and save Glasglopolis.
Oli Norman, CEO of itison and GlasGLOW creator, said:
“The past 18 months have been incredibly tough for everyone, that’s why we believe now more than ever in incredible experiences to enjoy together.
In October 2020 we managed to put on GlasGLOW for over 90,000 event goers making it Scotland’s largest outdoor activity. The odds were stacked heavily against us, but we brought light to the dark winter months.”
Whilst the exact details of this year’s show are under wraps, itison will be investing a seven-figure sum to create a world-class show and have promised the return of some of the most loved elements including Marshmallowland.

Early bird tickets will go on sale next Wednesday 25th August at 7.30am, exclusively at www.glasglow.com and after three sell-out years in a row, you better be quick to set your alarms.
Oli Norman added:
“Now, with COP 26 coming to Glasgow and the eyes of the world on our home city, we’ve created a brand-new spectacular for locals and visitors alike, one that reflects our response to the climate crisis in a fun and engaging way.
“I can’t give too much away, but we’ll be counting on you to help uncover the source of the toxic gloop and save our city!”
The show will also see the return of the itison Pumpkin Fund – the community engagement initiative which sees thousands of tickets donated to families who needed it most and funds a capital project in the city. This year itison will also be helping fund a local capital project supporting young people, sustainability and helping educate on climate crisis.

itison will be revealing trailers over the coming days with more details of what to expect, so make sure you’re following itisonGlasGLOW on Facebook and Instagram. And set your alarms for next Wednesday 25th August at 7.30am to bag yourself tickets at www.glasglow.com
