Festival of Lights

Signal Festival

Prague, Czech Republic

Oct 16 - 19, 2025ConfirmedSource

Each October, the city of Prague glows after dark for the Signal Festival, four nights of light art and creative technology. Glowing installations and great projections wash over the facades of historic buildings and squares, drawing crowds through the city center, in the Czech capital's largest celebration of the contemporary arts.

Media proof note

The Festival of Lights record is date-tracked, but stronger reviewed Field Guide media would make it easier to inspect.
