The tallest smokestack in Toronto looms over the Portlands, in stark contrast to the high-rise gentrification of its neighboring areas. Built in 1951, the R.L. Hearn Generating Station helped power the city for over 30 years until its decommissioning. This enormous relic epitomizes the ugliness of neglect, but inside the leftover machinery, labyrinthine skeleton, and the sheer scale inspires a sublime sense of awe.

There has been talk of repurposing the structure, and Hollywood's location scouts often select Hearn as a backdrop ("Robocop," "Red"); but in the meantime Tate Modern remains the best realization of such potential.
