The central location of the former military headquarters illustrates the importance of the infantry garrison in early Fredericton. Officers' Square, now a pleasant park, was formerly a parade ground. It is the site of the former officers' quarters, a three-storey stone building with white arches, constructed in 1839 with additions in 1851. A little further west, the Guard House (1827) and soldiers' barracks with red-painted wooden terraces have been restored and furnished.
