Origins and Norman Foundations
Rochester Castle’s story begins shortly after the Norman Conquest of England in 1066. William the Conqueror’s victory at the Battle of Hastings led to the rapid Norman consolidation of power across England. To secure his new kingdom, William and his barons established numerous castles, especially along key routes and strategic points.
Rochester, an important Roman and Saxon town, was a vital gateway to London via the River Medway and the main road, Watling Street. Recognizing its strategic importance, Odo of Bayeux, William’s half-brother and Bishop of Bayeux, constructed the first fortification at Rochester around 1087.
This initial castle was a motte-and-bailey design typical of early Norman castles. A wooden keep sat atop an earthen mound (the motte), with a protected courtyard (the bailey) below. The castle served as both a military stronghold and an administrative center for the surrounding lands shutdown123
