Historical Insight

Fortification to Feasting: The Great Defensive Evolution

Prior to the widespread deployment of siege cannons in the 15th century, European castles prioritized sheer verticality, concentric curtain walls, and impenetrable portcullises. As gunpowder rendered stone battlements vulnerable, monarchs repurposed royal wealth into palatial pleasure retreats with symmetrical manicured gardens and vast glazed gallery halls.

Our architectural guides trace this profound transition across France, Germany, Scotland, and Central Europe, detailing structural engineering, secret subterranean escape routes, and diplomatic throne chambers.
