Where Are Castles Located? Strategic Siting Across History

Castles were not placed randomly. Their locations were calculated for defense, control, and symbolism. Common siting principles:

Topographic Advantages

• Hilltops / Promontories: Natural elevation = visibility, defensibility (e.g., Edinburgh Castle on Castle Rock, Hohenzollern in Germany).
• Rivers & Waterways: Control transport, trade, supply; moats (e.g., Tower of London on Thames, Château de Chinon on Vienne).
• Coasts / Harbors: Naval control, trade protection (e.g., Dover Castle, Kronborg / Elsinore).
• Mountain Passes: Control movement between regions (e.g., Chillon Castle on Lake Geneva, Hohenwerfen in Austria).

Political & Economic Nodes

• Capitals & Royal Centers: Wawel Castle (Kraków), Prague Castle, Alcázar of Segovia.
• Trade Route Junctions: Marksburg (Rhine), Carcassonne (Languedoc).
• Religious Sites: Mont Saint-Michel (abbey-fortress), Angkor Wat (temple-mountain complex, Cambodia).

Evolution

Early motte-and-bailey (earth/wood) → stone keeps → concentric castles → palace-fortresses → artillery forts (star forts). Many later became palaces (Neuschwanstein, 19th-century Romantic revival) or prisons (Tower of London).

Location tells the story: a castle on a border speaks of conflict; one in a city center, of authority; one on a cliff above a river, of toll collection. They are geography made political.
