It's a long way from Sinking Spring Farm

The figure of Abraham Lincoln, with a freed slave giving thanks at his feet. The black man holds a book, indicating that he is not only free, he is also now educated. This was the first statue to an American President in any country outwith the USA. It is the only statue of Lincoln in Scotland, and the only monument to the American Civil War outwith the USA. The monument was erected at American expense to a small group of Scots who fought for the Union in the American Civil War. The inscription, "To preserve the jewel of liberty in the framework of Freedom" is a quotation from the writings of Abraham Lincoln.
