They replaced the rather primitive French stockade with a new, much more solid fort, guarded by 18 cannons and surrounded by a dry moat. They named it Fort Amherst, after Field Marshal Jeffrey Amherst who was Commander-In-Chief of the British forces in North America.
Though the fort is no longer standing, the dry moat is still there, surrounding a field full of sunken hollows, which mark the places where the cellars of the fort were.
