Greenbank House was built in 1763 by Glasgow merchant Robert Allason, who began life as a baker before setting up with his brothers in Port Glasgow as a trader. He made his fortune trading with Britain’s American colonies, eventually becoming a landholder in the Caribbean. The profits from trade in both tobacco and slaves allowed him to purchase Flenders Farm (land his family had worked for centuries), and establish the house. However, Allason’s trading interests later suffered during the American War of Independence. A small collection of portraits is on display in the house, along with a still life by the Scottish Colourist Samuel Peploe.
