In 1846, the British military began construction of Albert Barracks on 22 acres. The military post was occupied by various regiments – up to 1,000 soldiers – until 1870. Then the buildings were demolished and only 279 feet of the defense walls were left behind. Soon afterwards, most of the land was repurposed for the University of Auckland. 15 acres were reserved for Albert Park. This band rotunda was constructed in 1901.
