On the 26th and 27th of May, there's a multi-period reenactment event being held at Hunton Court in Kent (in the UK), to benefit Help for Heroes. The bulk of reenactor attendees are Napoleonic, to the best of my knowledge, but the point of it is to draw the public out for the weekend and to put on a good show for them. And, obviously, try to raise some money for H4H. If there is anyone in the Southeast, or the broader UK, who may be interested in attending, the event is open and free to the public.

More information can be found here. (Be warned that there is music embedded on the page, so if you're watching/listening to something, you might get blasted a bit.)
