Ski organisers in Zermatt say they want to 'show solidarity with all the people who are currently suffering and are grateful to all those who are helping to overcome the crisis'.
Switzerland, which borders hard-hit northern Italy, yesterday became the fifth European country to record 10,000 cases of the virus.
The illumination was set up by Swiss light artist Gerry Hofstetter and is being broadcast on webcams so that people can watch without leaving their homes.
As well as the English words, the projection has also displayed a heart, an image of the Swiss flag and a German-language call for 'solidarity'.
The tourist resort has been shut down until at least April 19 because of the pandemic, bringing its cable cars, mountain railways, and ski lifts to a halt.
