We chanced upon the Round House during a morning walk. Had a chat with Allan, one of the volunteers, and decided to go in. Our visit coincided with a bunch of school kids who obviously enjoyed their school excursion. Other volunteers would sidle up and explain a feature if we showed an interest. I took a photo of my wife with a "I'm guilty" and her prison number, later she was-placed in the stocks. I am surprised how long the site maintained our interest. The excellent volunteers with their historical knowledge bring the place to life - well done them.
