The Siege of Rochester Castle in 1215, recreated through Blender 3D animation, animated maps and real footage of the castle today. Follow King John's army as it attacks a fortress built to resist assault—and discover why bringing down a corner of the keep still did not end the siege.

Set during the First Barons' War, this medieval history documentary explores the struggle for Rochester's Medway crossing, the castle's layered defences, siege engines, undermining and the hunger that finally forced the garrison to surrender.

Step inside the keep to understand its raised entrance, forebuilding, portcullis, internal wall, stores and well. Then follow the attack from the outer bailey to the tower, the timber-supported mine and the collapse of the south-east corner. The story ends with the surviving architecture and the mark the siege left on Rochester Castle.

For history enthusiasts, this is a visual explanation of medieval siege warfare and castle design. For Blender and animation viewers, it is a finished historical reconstruction using 3D environments, animated characters, architectural cutaways and cinematic camera movement, combined with After Effects map animation. This is a documentary, rather than a Blender tutorial.

HOW THIS FILM WAS MADE
3D scenes were built and rendered in Blender; maps were animated in Adobe After Effects. Editing and sound work used Premiere Pro, Audition and Descript. AI tools assisted research, scripting and software automation within a creator-directed production workflow. The reconstructions are illustrative: exact troop positions, individual actions and some details of the lost interiors are not known.
