Rochester Castle


Rochester Castle, located in Kent, England, was first constructed shortly after 1066 CE by the Normans, was converted into stone between 1087 and 1089 CE, and then added to over subsequent centuries, notably between 1127 and 1136 CE, and again in the mid-14th century CE. The imposing castle keep or donjon seen today was added in the 12th century CE and is one of the best-preserved and tallest of any medieval castle. Odo of Bayeux, half-brother of William the Conqueror (r. 1066-1087 CE), was a famous resident as well as the bishops of Rochester. In 1215 CE Rochester was the scene of a major siege by King John of England (r. 1199-1216 CE) when rebel barons temporarily took over the castle. Today the site is managed by English Heritage and is an important surviving example of 12th-century CE castle architecture.
