One of the most famous examples of a Stewarts Folly is the Lennoxlove House in Haddington, Scotland. The house was built by the 1st Duke of Richmond and Lennox in the 17th century and was considered to be one of the most luxurious and expensive houses in Scotland at the time. However, the Duke's extravagant spending led to financial difficulties, and he was forced to sell the house and most of his estates.
Another example of a Stewarts Folly is the Brodick Castle on the Isle of Arran in Scotland. The castle was built by the 1st Duke of Hamilton in the 16th century and was intended to be a luxurious hunting lodge. However, the construction costs of the castle were enormous, and the Duke was forced to abandon the project before it was completed. The castle remains unfinished to this day.
The term "Stewarts Folly" has come to be used more generally to describe any project or undertaking that is considered to be extravagant or unwise, and which results in financial loss or negative consequences. It serves as a cautionary tale against excessive spending and reckless decision-making.
