A British architectural masterpiece Norman Romanesque, Rochester Castle guards London Road against its bumps along the Midway River. The durable structure is a square robe made of Kentish stone and was erected during the reign of Henry I in the 1120s. This three-story building is only more than 35 meters long, and its entrance is protected by an extension that allows attackers to climb narrow stairs. In some places, the promontory wall was four meters thick and tested in three sieges. King John succeeded in weakening the southeast using fire that began with lard in 1215. In the chapel, you can find examples of what the 14th-century Rochester Castle was like, while the palace courtyard featured open-air theater and cinema shows throughout the summer.
