The British Residency was the place that served as a refuge for approximately 3000 British inhabitants during the time of the uprising of 1857. Lucknow was center of all British activities during the siege and the Residency became the monopolistic center of the British for almost 90 days.
The Residency, today, bears testimony to the event known as the Siege of Lucknow which took place in 1857. The walls still bear the marks of cannon balls and bullets. The Residency now has a museum and hosts a light and sound show in the evenings. Photos sourced from Tripoto
