Black Hole of Calcutta, Historic prison in India
The Black Hole of Calcutta was a small dungeon located in Fort William, Kolkata, India.
In 1756, it was the site of a tragic incident where 123 out of 146 prisoners died due to suffocation and heat exhaustion.
This event has been widely referenced in literature and is a significant part of Indian and British colonial history.
Today, a memorial plaque stands at the site, serving as a reminder of the incident.
Despite its name, the 'Black Hole' was actually a small room measuring about 14 feet by 18 feet.
