StoneKeep Atlas
The World’s Atlas of Castles,
Fortresses & Historic Strongholds
We’re building the most comprehensive castle reference in the world the only way it can be done well — one country at a time.
Thirty-one German castles are live, fully researched and cross-referenced. More will come. Then, France and the rest of Europe follow.
StoneKeep Atlas is a growing reference dedicated to the world’s castles, fortresses, palaces, and fortified sites. Each entry goes beyond surface descriptions to explore the historical forces, architectural decisions, and human ambitions that shaped these places — from medieval hilltop strongholds to Renaissance royal residences.

Built on Curiosity, Not Shortcuts
StoneKeep Atlas exists because the world’s castles deserve better than surface-level descriptions and recycled paragraphs. Every guide on this site is researched from primary and scholarly sources, written with care, and built to help you understand not just what a castle looks like — but why it was built, who shaped it, and what it meant.
Independent, self-funded, and built on genuine curiosity.
