It has turrets equal in height to Cardiff Castle and is taller than the Great Wall of China.
And this summer visitors to Dreamland Margate will find out what it's like to have a go on the world's biggest bouncy castle when it enjoys a two-week stay at the Thanet theme park.
The mammoth inflatable will be at Dreamland between Saturday, August 12 and Saturday, August 26.
Open to visitors from 11.30am on every day of its stay, a 10-minute bounce will cost £3.50 or £3.00 for Dreamland Members.
Tickets are now on sale.
Created by the teams at House of Bestival and Something Creatives, the castle is filled with 1143 cubic metres of air and measures an epic 21 metres square.
Both adults and children can enjoy the bouncy castle, which comfortably accommodates 100 people at one time.
Chris Snelson, programming and events manager at Dreamland Margate, said: “We are so excited for the bouncy castle to come to Dreamland this summer.
"Whether you’re a family or even on a company day out - imagine jumping around with up to 99 other people - it’s going to be so much fun.”
Tickets now available via dreamland.co.uk. Group options for private hire are, say the theme park, available.
