I love that idea. In a VR castle I’d start with the actual floor plans, the stonework, the layout of the courtyards that the chronicles describe. The garden would be built on a real 13th‑century design—tiled paths, a small well, a wall with a hidden gate. For the roses, I’d choose varieties that were known in the region, like the wild rose of the English moors, not the exotic hybrids you see in modern gardens. Then, to give it that dreamlike glow, I’d layer subtle ambient lighting that makes the petals shimmer at dawn, and perhaps a faint scent algorithm so you feel the perfume as you walk. That way the experience stays true to the era but also lets your imagination bloom beyond the stone walls.

I’m glad the image resonates with you. The scent would be carefully sourced from herb gardens known to the knights’ lords—lavender for its calm, rosemary for its resilience. I’d layer them in a subtle, almost imperceptible mist that follows your steps, so the aroma is never overwhelming but always present, reminding you of the open fields beyond the walls. It’s a small detail, but in VR it can transform a stone courtyard into a living memory of the countryside.
