TORONTO — In just three and a half weeks, workers here built one of the world’s largest cultural performance spaces inside an abandoned power plant. There are stages for theater, dance and music, as well as multiple art galleries and a high-end French restaurant.

And after 17 days, they’re going to tear it all down.

The temporary site was built for the 10th edition of the Luminato Festival, which opened on Friday. It is the first time that the festival has located all of its ambitious programming in a single place: the Hearn Generating Station in Toronto’s industrial Port Lands area.

The festival includes the only North American performances of the National Theater of Scotland’s trilogy of “The James Plays”; the immersive “Situation Rooms” of the Berlin theater group Rimini Protokoll; and the thunderous Unsound Festival. Music events span the sonic spectrum, from Beethoven to a queer hip-hop dance party. And the power plant’s former control room has been transformed into Le Pavillon, an ode to the storied New York restaurant of that name. Around 850 artists are participating in 162 events; last year’s festival drew more than 600,000 visitors.

Jörn Weisbrodt, the outgoing artistic director of Luminato, described the Hearn, which was decommissioned in 1983, as a creative achievement. “It’s an artwork in itself,” he said. “It’s not just a venue.”
