William the Bastard and his stormin' Normans defeat Harold Godwinson and his underdog Anglo Saxons in October of 1066, a victory that laid a foundation for everything from the British Empire and the 13 American colonies to a trivial little thing called the English language. Battle Abbey marks the site where Harold was allegedly slain during the battle. A new multimedia visitor center and 60-minute audio tour across the battlefield are the best ways to learn about the conflict that laid the groundwork of modern England.

Two of the iconic clashes of the Middle Ages were fought around this tranquil town in central France. The first battle (732 A.D.) thwarted the Islamic threat against Western Europe; the second (1356 A.D.) foreshadowed the decline of chivalry in favor of modern warfare. The modern city of Poitiers boasts many architectural gems from the period between the two battles. Get into the mood even more by sleeping at the 16th century Chateau de la Guillonniere, about 15 minute's drive from both killing fields.

The movie "Brave Heart" might have been more cinematic, but the real "last stand" of the Highlanders was the Battle of Culloden in 1745 between the Scottish Jacobites under the command of Bonnie Prince Charlie and the invading English. Waged on a wind-swept moor near Inverness, the defeat and its brutal aftermath decimated the clan system for all time. The battlefield is marked by stone monuments erected not long after the conflict and the best battlefield museum in Europe—a brand new, interactive visitor center that opened last December. Visitors can spend the night at Culloden House, the country manse where Bonnie Prince Charlie slept before the battle.

It wasn't the first, last or most famous clash of the American Revolution, but the 1777 Battles of Saratoga turned the military tide in favor of the rebels, boosted colonial confidence and brought France into the war as an economic and military ally. Saratoga National Military Park boasts a small museum and a self-guided trail to various places where the fighting took place. Nearby Saratoga Springs—with its posh restaurants, shops, spas, racetrack and historic hotels like the Saratoga Arms—is the place to base your battlefield visit.

The history of North America might have been radically different had Hernan Cortés and the Spanish not captured the Aztec capital of Tenochtitlán (Mexico City) in the early 1520s. The series of clashes lasted for nearly two years with much of the action taking place on the causeways that linked the then-island city to the mainland. The ruins of Templo Mayor near the Zócalo plaza mark the spot where a major massacre of Aztec nobility took place, while the Avenidas Tacuba and Hidalgo running west from the temple follows the path of a causeway where major events of the battle played out.

The legendary siege of Troy may or may not have taken place in northwest Turkey around 1,200 B.C., but that hasn’t prevented local authorities from erecting a reproduction Trojan Horse near the ruins of the ancient city. The most important part of the citadel is now protected beneath a giant sail-like canopy. Although marked by multilingual signs, the ruins and battlefield are best explored with local guides who can separate fact from fiction.
