They reopened it, at it's 21st birthday in 1947. There's fantastic footage of it here:
Saw a mention of it in this week's Folkestone Herald. I always believed they did the official opening of it, though never thought to look it up...
This is part of my site The 'Gerald that I built in a fury of excitement when I first came here in approximately '04. I'd been a frequent visitor for a few years before that but I am technically one of those Down From Londons you get nowadays. The site was a lot more dynamic with a calendar of events and voting for favourite venues and stuff, and I know it was a handy resource for others who were moving here. Now I've moved out of Folkestone again (though only to Hythe) it doesn't get as much attention as it used to. Ironic really as Folkestone itself is becoming the exciting place we always thought it was just about to. My name is not Gerald BTW, the name comes from the name of a pretend paper in an episode of The Day Today or something, the Portsmouth Gerald, and how there is a local newspaper here called the Folkestone Herald. Puns like this are GRATE aren't they? Do contact me if you have anything to offer, email anythign @ this domain, or try @folkestone or @pauly on the twitter.
