Besides the cultural center/Folk Park in Bunratty, are there any other cultural centers in Ireland where people wear period clothing and reenact life in medieval Ireland? We have visited Plimouth Plantation in Massachusetts (Pilgrims) and New Salem in Illinois (Lincoln) and get a real kick out of seeing just how difficult life was back in the "good old days" - and we occasionally even learn something.
I will give you a list of some of them. Keep in mind that it depends on time of year as to whether there are people in costumes there. In the off-season they cut back on that.
