INDIA: In a striking confluence of heritage and high-performance visual technology, Christie has brought its RGB pure laser projection prowess to the fore at Rani-ki-Vav, the 11th-century stepwell and UNESCO World Heritage Site in Patan, Gujarat. Commissioned by the Government of Gujarat and inaugurated by Indian Prime Minister Narendra Modi on March 31, the large-scale light and sound show transforms the 500-foot-long subterranean monument into an immersive storytelling canvas; marking one of the most technically sophisticated projection mapping installations ever realised at a heritage site in India.

Widely regarded as one of the world’s most extraordinary subterranean architectural marvels, the façade of Rani-ki-Vav is illuminated using 10 Christie RGB pure laser projectors, including the Griffyn 4K35-RGB and M 4K25 RGB models, each delivering up to 36,500 lumens. The deployment leverages true 4K resolution and an expansive colour gamut to render the monument’s intricate carvings, nuanced stone textures, and delicate tonal variations — from warm sandstone hues to deep indigo nightscapes — with exceptional fidelity.

The project was supported by Design Factory India as consultant, with Aura Bright Light responsible for the supply and installation of the projection system, while Knownsense Studios led the creation of content. The monument was digitally captured and mapped onto a massive 22,000-pixel-wide content canvas, one of the largest ever developed for an Indian heritage site. A multidisciplinary team of artists, animators, and heritage researchers collaborated to craft a visual narrative that reflects the story, philosophy, and cultural essence of Rani-ki-Vav.

Operating under stringent guidelines set by the Archaeological Survey of India (ASI), the project required a zero-intrusion approach, prohibiting any permanent or visible structures. This led to the engineering of a bespoke solution featuring hydraulic lift-based projector mounts concealed below ground. Each unit rises six metres (19.6 feet) into a precisely pre-aligned position during showtime and retracts seamlessly afterward, ensuring both millimetre-accurate projection alignment and complete visual preservation of the site during daylight hours.

“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.”

Blending motifs inspired by Patan Patola textiles, ancient water architecture, and spiritual symbolism, the show integrates projection with an evocative soundtrack and narration. Traditional Indian instruments merge with cinematic orchestration, echoing the rhythm of chisels and flowing water to guide audiences through themes of creation, devotion, and rediscovery.

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 color 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 integrating 4K RGB pure laser projection with ultra-high-resolution content and culturally grounded storytelling, the Rani-ki-Vav installation underscores a growing shift in India’s heritage presentation landscape; where advanced visual technologies are being deployed not merely as spectacle, but as a means of deepening cultural engagement while preserving architectural integrity.
