Wallingford Castle began around 1067 as a major Norman fortress ordered by William the Conqueror, quickly becoming one of England's most strategically important royal strongholds on the River Thames. Throughout the medieval period, the castle evolved from its original motte-and-bailey design into a sophisticated fortress with a stone shell keep within high curtain walls and impressive earthwork defenses. The castle played a central role in English history, notably as a refuge for Empress Matilda during the twelfth-century civil war with King Stephen, and later as a renowned venue that hosted one of the largest medieval jousting competitions ever held. Though the castle fell into decline centuries ago, its earthworks and castle grounds survive as a reminder of its considerable medieval importance.
