William Alexander (the younger)

Sir William Alexander (c. 1602 – 18 May 1638) was the founder, in 1629, of the Scottish colony at Port-Royal, now the site of modern Annapolis Royal. He also built forts in Cape Breton then in Port Royal. He was the son of colonizer William Alexander, 1st Earl of Stirling, but predeceased his father and never assumed his title.

For many years the site of Alexander's settlement, known as Charles Fort or Scots Fort, was thought to be on the hillside overlooking the Habitation. This site, marked by a stone monument and brass plaque, was designated a National Historic Site of Canada in 1951. The plaque has been removed and relocated as the actual site of Charles Fort has been established through archaeological evidence at Annapolis Royal; lying beneath Fort Anne.
