Top five castles of Extremadura, Spain

Spain is one of the best countries in the world to see castles. Throughout the Middle Ages, the Iberian peninsula was split between various Christian states and the Moors, Muslim invaders from North Africa. These factions fought and traded with each other in a constantly changing network of political alliances. Leaders protected their domains with castles and walled cities. One of the hot spots for fighting was in the southwest in what is now the autonomous community of Extremadura, including its provinces of Badajoz and Cáceres. There are literally hundreds of castles here. Below are five of the best, picked for their accessibility and general coolness.

Olivenza
Olivenza is a town in the province of Badajoz. It's right on the border with Portugal and is actually claimed by that country, although it has been under Spanish jurisdiction since 1801. The castle of Olivenza is an impressive Templar fortress adapted from an earlier Muslim castle taken in 1228. It features high walls and imposing square towers. As you can see from the photo in the gallery, these included "murder holes" set out from the edge of the tower from which to drop rocks and boiling water on attackers. The idea of dropping boiling oil is a myth. Water was much cheaper and easier to obtain, although one account from a siege in France talks about using boiling lead! The castle at Olivenza was expanded in the 14th and 16th centuries and is very well preserved, still dominating this small town of 12,000 people. A gate flanked by slender, semi-round towers, and a wide moat also survive.

Fregenal de la Sierra
This castle is also in Badajoz and guards the road to Seville. As you can see from the above photo, courtesy Fregenal01 via Wikimedia Commons and taken under much better conditions than the crappy weather we had on our trip to Extremadura, the high walls and seven towers now share the skyline with church spires. This wasn't always the case. The first fort here was built by the Romans, later reworked by the Visigoths and Moors. After the land was taken from the Muslims, King Fernando III gave the castle to the Templars in 1283. They expanded and improved the fortifications and they were still being used as late as 1808 by Napoleon's troops! The castle courtyard is now the town's bullfighting ring.
