The Great Blacks in Wax Museum was the first wax museum about black history. It first opened in 1983 with 21 wax figures and it has grown and expanded over the years and now houses over 140 wax figures. The museum not only shows well known events in black history, it also shows regular every day lives of blacks. Some of the exhibits include Harriet Tubman, the Underground Railroad, a slave ship, Egyptian rulers, and many other wonderful exhibits. It's such a great museum and there is so much to learn.
Side note: It's chilly there b/c if it gets too warm the wax will melt, so you may want to bring a sweater.
