 Demand for land, public animosity toward the stockade and prison reform led to the stockade's closure.All prisoners were transferred to the new prison at Pentridge, and in August 1866 the stockade became an asylum, initially for mentally ill prisoners from other jails, and then as a public asylum with both short- and long-term wards.In 1868 Collingwood ceased to admit acute patients who had previously been retained in the gaols.
