GOLDEN VALLEY, Minn. - A man's home is his castle but could it withstand an attack by Ragnar and the Vikings, Alexander and the Greeks, or Genghis Khan and the Mongols?

Why settle for an electronic home security system when you can defend your castle like a king?

Backyard Ballistics author William Gurstelle poses this fascinating question to modern-day garage warriors in his book, Invading the Castle, and shows KARE 11 News @ 4 viewers how to build an arsenal of ancient artillery and fortifications aimed at withstanding these invading hordes.

According to Gurstelle, each chapter introduces a new bad actor in the history of warfare, details his conquests, and features weapons and fortifications to defend against him and his minions.

Clear step-by-step instructions, diagrams and photographs show how to build a dozen projects, including "Da Vinci's Catapult," "Carpini's Crossbow," a "Crusader-Proof Moat," "Alexander's Tortoise," and the "Cheval-de-frise."

With a strong emphasis on safety, the book also gives tips on troubleshooting, explains the physics behind many of the projects, and shows where to buy the materials.

By the time readers have reached the last page, at-home defenders everywhere will have succeeded in creating a fully fortified home.

Or at least be entertained.
