Karak Castle, also known as Kerak Castle, is a large crusader castle located in Karak, Jordan. It's perched on a steep hilltop and is a significant example of the Crusaders' architectural military genius. The castle's origins date back to the 12th century when it was built by the Knights of King Baldwin I of Jerusalem to expand their power over the transjordanian region. This fortification was strategically important due to its position along the Kings' Highway, where it could control trade and military movements. Karak Castle endured numerous sieges and changed hands several times throughout history, including between the Crusader and Muslim armies. Its walls have witnessed the famous battle of Hattin and the formidable leadership of the Kurdish-Ayyubid Sultan Saladin. Despite earthquakes and battles, substantial portions of the castle remain intact, allowing visitors to explore its underground galleries, towers, and ramparts. The castle's design is a testament to the evolution of military fortifications before the age of gunpowder. Within its walls, there are also remnants of a more civilian nature, including a chapel, royal quarters, and dining halls. Archaeological discoveries in Karak Castle further provide insights into the lives of those who dwelled within.
