In 1919, the British under the command of General Dyer fired randomly on a peaceful gathering of people in demand of freedom, resulting in hundreds of men, women and children killed on the spot. The bullet marks on the boundary walls bring alive the agonizing tale of cruelty of the British rule. This event was one of the major incidents of India's freedom struggle. The memorial well is also present here in which some people jumped to escape the firing. The story of the massacre is told in the Martyr's Gallery at the site..
