1: Bacon’s Castle:

Constructed in 1665, Bacon’s Castle is the oldest in the United States of America. It is the only surviving Jacobean architecture in the New World. 

The Bacon’s Castle goes by diverse names. It is either called the Allen’s Brick House or Arthur Allen House. Arthur Allen built the house in scenic Surry, Virginia, when he was 57. 

Why the name “Bacon’s Castle?” 

The name “Bacon Castle” has undoubtedly become more popular than “Arthur Allen House,” the name of the man who built the house. The reason was that Nathaniel Bacon’s supporters used the castle in 1676. It was used during Bacon’s Rebellion, an armed rebellion by Virginia settlers between 1676 and 1677.

Contrary to claims, there has been no account of Nathaniel Bacon’s presence in the Arthur Allen House. He didn’t step foot in the house or live there his entire life.
