Ulster American Folk Park

This brilliant video is of 2006/7 American War of Independence events at the Park featuring English and Northern Irish reenactors plus of course the German Oneida Iroquois group - award winning photos and video from Keith Campbell.

One of the best places to reenact colonial America over here on this side of the pond is surprisingly in Northern Ireland! The Folkpark in Omagh is the home of many reconstructed buildings such as this log cabin which with its snake fencing is a brilliant backdrop for action and the Park usually has a colonial reenactment around the 4th of July.
