Let AI illustrate the setting. Keep the names, grid and finishing touches in your hands.
Describe the terrain and landmarks, then choose parchment, watercolor, ink or painted art. Prompts request no lettering, so you can name places yourself instead of fixing AI text.

A stronghold surrounded by water.
Strongholds & secrets
Let the terrain shape the stronghold.
Choose a landscape and a defensive purpose. A cliffside keep needs a different approach than a river fortress. These are location illustrations, not dimensionally accurate floor plans.
- Choose the defensive site: a cliff, river island or mountain ridge. Describe the approach before the towers.
- Specify the exterior spaces that matter: a gatehouse, outer courtyard, inner keep and gardens. Keep rooms and interiors for a separate planning process.
- Inspect access from the road through the gates. Add courtyard and tower names afterward; do not infer room dimensions from painted rooftops.
Try this prompt: A cliffside stone castle with two courtyards, a narrow bridge, terraced gardens and a village at its gate. No text or labels.

Choose the view that helps you plan, write or play.
A seat of power in your story
Use courtyards, walls and gardens to establish a stronghold’s character. This exterior view does not define rooms, stairs or interior dimensions.
FROM YOUR SCREEN TO YOUR STORY
Take the map with you.
A downloadable image, not a locked-in project format.
Keep the original
Download the clean image before adding annotations. Export a separate PNG from the editor for each version you want to share.
Use it in your VTT
Import a PNG as an image in Roll20 or Foundry. Choose grid dimensions and pixels per cell in the editor, or export without a grid.
No scene files, walls, lighting or automatic grid alignment.
Prepare a handout
Set your output dimensions, then place the PNG in your layout or print workflow. Check the result at its intended size before printing.
Larger canvas dimensions do not add detail to the source image.

BEFORE YOU SET OFF
A few things to know.
Does this generate castle floor plans?
No. It creates exterior castle and grounds illustrations. Rooms, stairs, wall thickness and floor-to-floor alignment are not provided as an accurate plan.
Can I create a ruined fortress instead?
Describe collapsed walls, an overgrown courtyard and a broken approach road. Review the image for usable entrances rather than assuming every drawn passage connects.
Is the fantasy map generator free?
Grid overlays, labels, compass marks and PNG export are free and run in your browser. AI generation uses credits; monthly plans have a fixed allowance, not unlimited generation.
Why are there no place names in generated maps?
AI lettering can be unreliable. Prompts explicitly request no text. Add your own readable names in the free browser editor instead.
