Nature & Technology


Projektil partnered with Bad Ragaz Tourism and the Cantonal Office for Economics and Labour St.Gallen to create an innovative attraction at the canyon where the naturally heated water that made famous Bad Ragaz emerges.

During summer 2017 we turned the spectacular Tamina Gorge near Bad Ragaz into the world’s largest natural projection screen.

The show was a complete success and was sold out every day for 2.5 months.

And we will be back in 2018! On June 4th, reality and illusion collide once again and breathe new life into the rocks of the Tamina Gorge every evening until the end of September 2018. Light Ragaz opens its doors to another dimension at 6 pm every evening and entices the visitor with its enchanting beauty of the Swiss nature in a singular symbiosis with cutting-edge technology made in Switzerland.

Large-scale 3D mapping at Tamina George

We created a multimedia event that uses cutting-edge technology to project 3D effects onto the structures and formations of the rocks of the Tamina Gorge with millimetric precision.

The raw rocks reach up to 80 meters. The nightly transformation of the canyon, of almost 1000 meters in length, into a visually stunning sea of light and colour, brought many technical challenges. It is an aggressive environment for hardware, very humid and rough. So we decided to implement a semi-permanent installation with a high-speed fibre-optic network and tailor-made outdoor casing for the 20+ projectors that are part of the show.
