The 11th-century stepwell Rani‑ki‑Vav, a UNESCO World Heritage Site in Patan, Gujarat, has been transformed into a breathtaking canvas of light, colour, and storytelling thanks to Christie® RGB pure laser projectors. Commissioned by the Government of Gujarat and inaugurated by Prime Minister Narendra Modi on March 31, the immersive projection mapping experience spans the 500-foot-long subterranean monument, marking one of India’s most ambitious digital heritage showcases.
Ten Christie RGB pure laser projectors, including the Griffyn 4K35‑RGB and M 4K25 RGB models, bathe the stepwell in vivid colour and brilliant contrast, delivering up to 36,500 lumens per unit. The 4K resolution and wide colour gamut faithfully render every carving, texture, and subtle hue, from warm sandstone to deep indigo night skies.
Supported by Design Factory India as consultant, Aura Bright Light supplying and installing the projectors, and Knownsense Studios leading content creation, the installation maps 22,000 pixels across the stepwell, the canvas among the largest ever used for an Indian heritage site. Multidisciplinary teams of artists, animators, and heritage researchers developed visuals inspired by Patan Patola textiles, ancient water architecture, and spiritual symbolism, blending ultra-high-resolution 3D animation with evocative soundscapes that merge traditional instruments with cinematic orchestration.
Given the monument’s UNESCO status, strict guidelines from the Archaeological Survey of India (ASI) prohibited permanent or visible structures. To overcome this, hydraulic lift-based projector mounts were installed underground, rising six meters at showtime for millimeter-precise alignment before retracting afterward. Thus, ensuring the historic site remains visually unaltered by day.
“Rani‑ki‑Vav demanded a technological solution that could match the monument’s extraordinary craftsmanship,” said Siddharth Bathla, director and co-founder, Design Factory India. “Christie’s RGB pure laser projectors were the clear choice, delivering the resolution, brightness, and color fidelity needed to honor every carving and contour, while the concealed hydraulic infrastructure ensured the monument’s sanctity was fully preserved.”
Shailesh Patel, managing director, Aura Bright Light, added, “Executing a project of this scale within the constraints of a UNESCO World Heritage Site is a rare challenge. The innovative deployment of the Christie Griffyn 4K35‑RGB and M 4K25 RGB projectors on hydraulic lifts enabled us to achieve spectacular results with precise alignment, while adhering to every conservation guideline set by ASI.”
“We treated Rani‑ki‑Vav not as a backdrop, but as the protagonist of the story,” said Mandeep Sharma, head of Production and Animation, Knownsense Studios. “Christie’s 4K RGB projectors allowed our ultra‑high‑resolution content and 3D animations to blend seamlessly with the stone architecture, creating an emotional, immersive experience that feels both contemporary yet deeply rooted in history.”
Rishubh Nayar, ProAV sales director for India, Christie, commented, “This project exemplifies how technology can elevate heritage storytelling with dignity and precision. Our RGB pure laser projectors are designed for demanding environments where colour accuracy, fine detail, and long‑term reliability are non‑negotiable. Rani‑ki‑Vav powerfully demonstrates how light can connect past and present on a global stage.”
By combining 4K RGB pure laser projection, culturally authentic storytelling, and precise engineering, the Rani‑ki‑Vav light and sound show elevates digital heritage experiences in India. More than a spectacle, it is a living dialogue between centuries, a celebration of architecture, culture, and innovation that connects audiences to India’s legacy through light, sound, and storytelling.
