Great Castle Floorplans for RPGs and Worldbuilding

An index of floor plans for more than 200 castles and fortified houses across England, Scotland, Wales, Ireland, France, and Germany, including Dover, Edinburgh, Caernarfon, Chambord, Eltz, and Neuschwanstein. Each castle links out to its own page; check that page's own licensing and sourcing notes before reusing anything from it.

Why it is useful: Breadth is the point: instead of one plan, this is a starting shelf of real defensive layouts to browse by region until one matches the site a scene needs, from a compact border keep to a sprawling royal fortress.

Hand-drawn floor plans covering all six levels of the Biltmore House in Asheville, North Carolina, split into a lower-three-floors and an upper-three-floors view.

Why it is useful: At 175,000 square feet and 250 rooms, Biltmore is the largest private home built in North America, and the plan lays out exactly how a household that size actually functions: 21 servant rooms on the fourth floor, and a basement holding the swimming pool, bowling alley, kitchen, scullery, and laundry. That servant-and-service layer is what most fantasy palace maps skip, and it is the detail that makes a noble estate feel staffed rather than staged.

A hand-drawn floor plan of King Ludwig II's 19th-century Bavarian palace, the building that directly inspired Disney's fairytale castle. Covers the main tower, state rooms, and the hill-top footprint of a palace that was still unfinished at the king's death in 1886.

Why it is useful: This is the real building behind the generic 'fantasy castle' silhouette, so its floor plan is a shortcut past the cliché straight to specifics: a 213-foot main tower, a 426-foot footprint perched on a sheer 656-foot hill, and state rooms built for spectacle rather than defence. Useful as a direct model for a wizard's tower-palace or an eccentric noble's folly.
