The look of the Chittenden Locks has been greatly influenced by two men. Carl English, who transformed the empty lawns of the grounds into the botanical garden you see today, and Carl Gould, who designed several of the buildings and structures you walk among when you visit the locks. Sara Peterson has researched and written a piece on both of these men and here is an online version. Clicking on these images should give you a larger higher resolution image.
