Castles on the East Coast

Castles in the United States? Yes! Castles on the East Coast of the United States? Yes again!

The East Coast of the United States is a treasure trove of historical sites, and few things embody the region’s rich history more than the castles that dot the landscape. From Maine to Florida, these fortresses tell the story of America’s past, and offer a glimpse into the lives of the people who once called them home.

What is a castle?

It seems like an obvious question. It’s a towering fortress, typically from medieval times but also found in fairy tales. Some can be as elaborate as Peles Castle, which is technically a king’s palace, or as simple as a strategically positioned military fortress, like Bran Castle, the supposed inspiration for Dracula’s castle.

Can you tell I visited castles when I traveled to Romania?

In fact, castles are essentially fortified buildings typically used during medieval times. Since the United States wasn’t established until much later, you could argue that these east coast castles are simply fashioned in the style of castles. However you look at it, it’s fun to check out castle like buildings right here on the east coast.
