White Heron Castle (Himeji Castle) - UNESCO World Heritage Site
Generated by Grok AI
Creates a detailed, modular reconstruction of Himeji Castle (Shirasagi Castle),
Japan's largest and most beautiful feudal castle. UNESCO World Heritage Site.
Architectural Features:
- Five-story main keep (tenshu) with multiple roofs
- Three smaller keeps connected by corridors
- Seventy-four yagura (turrets) and towers
- Extensive stone walls and foundations (oshikiri)
- Multiple gates and defensive baileys
- Traditional Japanese castle architecture
- White plaster walls (gives "white heron" appearance)
Modular Design for VR/Resonite:
- Separate components for performance optimization
- Main keep, sub-keeps, towers, walls, gates
- Traditional Japanese roofing and detailing
- Stone foundation systems
- Interior and exterior components
