Lincoln Castle is an amazing place to visit with its complete circular wall that can be walked with great views of the nearby cathedral. It is rather unusual with two Norman mottes and its history of numerous medieval sieges. All the medieval sieges were of national importance and featured King Stephen, King Richard, King John and the nine year old King Henry III. In 1217, the castle was pounded by boulders fired from massive catapults known as trebuchets as part of the Battle of Lincoln. Victory of Henry III’s army led by the heroic, William Marshall, just outside the castle walls put an end to English rebels and French troops claiming the English crown for Prince Louis of France. Lincoln Castle, has its own copy of the original Magna Carta on display, an audio visual display explaining this highly important document and a small but fascinating museum. The castle grounds also house a Georgean and Victorian prison where original cells can be visited. Lastly, it even has its own resident dragon!
