Menstrie Castle is a three-storey manor house in the town of Menstrie, Clackmannanshire, near Stirling, central Scotland. From the early 17th century, it was home to Sir William Alexander, 1st Earl of Stirling, who was instrumental in founding the colony of Nova Scotia. It was later owned by the Holburn or Holborne family, who were created Baronets of Menstrie in 1706. The castle was restored in the 20th century, won a Civic Trust award, and now incorporates holiday accommodation, private flats, and a museum and cafe run by the National Trust for Scotland.
The castle was built around 1560 by the Alexander family, a branch of the Clan MacAlister, who had anglicised their surname. Sir William Alexander was born here around 1577, and later became known as a poet. He gained a place in the Royal Household of James VI, eventually becoming a member of the Privy Council of Scotland in 1615, Principal Secretary of State in 1626, and Earl of Stirling in 1633.
In 1621, he was appointed governor of Nova Scotia, an area of North America including the modern Canadian provinces of Nova Scotia and New Brunswick, and the Gaspé Peninsula. In order to populate his territory, the Baronetage of Nova Scotia was devised in 1624, whereby Baronetcies were sold to support colonists. The scheme was a financial failure, and in 1632 Nova Scotia was returned to the French, who had claimed the area originally. Alexander died bankrupt in London in 1644.
