Constitution Hill was one of the places that was involved in the Castle Hill convict rebellion. The mostly Irish convicts would travel from Castle Hill down modern-day Old Windsor Road and meet at Constitution Hill. The distraction they had made at Castle Hill (A fire (?)) was supposed to stretch out the government forces by allocating some men to go to Castle Hill. The convicts would then attack Parramatta (The head of the colony at that time) and take over control.
