See authentic arms and armor from Romans, Dark Age Warriors, Vikings, Crusader Knights, and Renaissance “Knights in Shining Armor.” New galleries cover American history from the Colonial Era through the late 1800’s and include a hundred period firearms. Open from 1-4pm on Fridays and Sundays and 10am-4pm on Saturdays.
