The Government House site was once the location of the 17^th century Acadian settlement known as Sainte-Anne. Located nearby is an earlyburial ground where both Wolastoquewiyik (Maliseet) and Acadian peoples are buried. Government House has had a varied and colourful history since the first cornerstone was laid in 1826 and the official re-opening in 1999.
