Three Key Defensive Features of Windsor Castle

Fortress Architecture at Its Peak

1. Massive Curtain Walls & Towers – Thick stone walls with crenellated battlements, mural towers, and arrow loops create a formidable shell.
2. Commanding Hilltop Position – Built on a chalk ridge overlooking the Thames, the site gives clear fields of fire and makes direct assault uphill.
3. Moat (Dry Ditch) – A deep, wide ditch surrounds the Upper Ward and Round Tower, preventing undermining and siege-tower approach.

Evolution

Originally a Norman motte-and-bailey (c. 1070), Windsor was continuously upgraded—Henry II's stone keep, Edward III's gothic palace, Henry VIII's gun ports—blending medieval strength with royal splendor.
