Where was Escape at Dannemora filmed?

Using smuggled hacksaw blades, they cut through the walls and steam pipes of the maximum-security Clinton Correctional Facility in Dannemora and exited through a nearby manhole.

Hiding from law enforcement, they led them on an exhausting chase through the North Country forests over the next three weeks that ended in gunfire miles from the Canadian border.

Director Ben Stiller recreated the scenes from that escape, which made international headlines at the time, in Showtime's “Escape at Dannemora,” now streaming on Netflix.

The series details the prison escape of David Sweat, played by Paul Dano; and Richard Matt, played by Benecio Del Toro; with the help of prison employee Joyce “Tilly” Mitchell, played by Patricia Arquette.
