Rochester Castle stands on the east bank of the River Medway in Rochester, Kent, South East England. The 12th-century keep or stone tower, which is the castle's most prominent feature, is one of the best preserved in England or France.

Situated on the River Medway and Watling Street, Rochester served as a strategically important royal castle. During the late medieval period it helped protect England's south-east coast from invasion. The first castle at Rochester was founded in the aftermath of the Norman Conquest. It was given to Bishop Odo, probably by his half-brother William the Conqueror. During the Rebellion of 1088 over the succession to the English throne, Odo supported Robert Curthose, the Conqueror's eldest son, against William Rufus. It was during this conflict that the castle first saw military action; the city and castle were besieged after Odo made Rochester a headquarters for the rebellion. After the garrison capitulated, this first castle was abandoned.

Between 1087 and 1089, Rufus asked Gundulf, Bishop of Rochester, to build a new stone castle at Rochester. He established the current extent of the castle. Though much altered through the centuries, some parts of Gundulf's work survive. In 1127 King Henry I granted the castle to the Archbishop of Canterbury in perpetuity. William de Corbeil built the massive keep that still dominates the castle today. Throughout the 12th century the castle remained in the custody of the archbishops.

During the First Barons' War (1215–1217) in King John's reign, baronial forces captured the castle from Archbishop Stephen Langton and held it against the king, who then besieged it. The Barnwell chronicler remarked "Our age has not known a siege so hard pressed nor so strongly resisted". After resisting for just over seven weeks, the garrison surrendered. Although the castle had been greatly damaged, with breaches in the outer walls and one corner of the keep collapsed, it was hunger that eventually forced the defenders' hand. The castle did not stay under John's control for long: in 1216 it was captured by the French Prince Louis, who was the new leader of the baronial faction. John died and was succeeded by his son King Henry III in 1216; the next year, the war ended and the castle was taken under direct royal control.
