Castle Icon - Fortress Symbol for Security, Strategy, and Medieval Themes #135322 (License: Personal Use)

This high-contrast vector-style icon depicts a stylized medieval castle tower with crenellated battlements, two square windows, an arched entrance, and a fluttering flag atop the central turret. Designed for clarity at small sizes, it conveys themes of protection, authority, and historical adventure. The monochrome palette ensures versatility across UIs, logos, and educational materials.

Commonly used in game UIs (e.g., territory control, base building), cybersecurity dashboards (symbolizing firewalls or secure zones), educational content about medieval history, or app icons for strategy/tower-defense games; matches user intent for visual metaphors of safety, sovereignty, or challenge.
